Deciding on a new project is rarely a simple task. it requires balancing two distinct questions: what do I want to create, and what does my audience want to build? Finding the right answer to these questions is vital, both to maintain my own passion for leathercraft and to ensure the final patterns resonate with the community. Developing a new pattern requires weeks of dedication to design, prototyping, crafting, and documenting the process. Consequently, moving forward with a project that ultimately proves unpopular can be both financially and psychologically taxing.
For this project, I knew I wanted to tackle an ambitious design. I have a deep affinity for architecture-inspired lamps and was eager to create a new one. While my previous designs – the mosque lantern and the lighthouse lamp – were personal favorites, they are niche pieces. I wanted to find a landmark with wider appeal. While playing Clair Obscure: Expedition 33, I encountered a cataclysm-struck version of the Eiffel Tower. Seeing it for the first time, I knew there was no better landmark to transform into a lamp. That inspiration led me to design this maquette – a 1:500 scale replica of the Eiffel Tower. The result captures the intricate lattice, the signature arches, and the detailed balustrades, all while featuring the ability to display stunning light shows.
A word of caution
This is a complex project in several respects. Please read through this tutorial entirely before purchasing the pattern to ensure you are ready to take on the challenge.
Let’s go through the main difficulties and the ways to simplify those tasks as much as possible:
Cutting the lattice facade: this is the first and most significant hurdle. I highly recommend using a laser cutter for these elements. If you do not own one, I suggest contacting a local fablab or makerspace. While I completed this maquette entirely by hand, please be aware that doing so is extremely time-consuming.
Painting the elements: the lattice features numerous small surfaces. Painting these by hand with a brush requires significant patience. If available, airbrushing will considerably speed up the process.
Stitching the tower: I initially expected the cutting to be the most tedious phase; I was wrong. The stitching proved to be the true challenge. In many sections, the tight angles make needle manipulation difficult and slow. Using curved needles in these areas is highly recommended.
Integrating electronics: adding LED strips introduces further constraints. If the structural build is challenging enough, you may choose to omit the electronics. However, the maquette is transformed when illuminated, and in my opinion, the result is well worth the added effort.
The support arches: during the design process, I had to ask myself: how much detail is too much? I felt the arches supporting the first, second, and third floors were at the absolute limit of what is reasonable to include, but I ultimately preferred the aesthetic with them in place. However, a practical observation: these arches are virtually invisible if the finished maquette is displayed below eye level. Given that this involves handling 80+ tiny pieces, you may want to skip this step to save yourself significant labor – or include them for the sake of completion. The choice is yours!
With all that being said, let’s dive into the construction of this one-of-a-kind illuminated Eiffel Tower maquette!
Ensure the pattern is not resized by checking your print settings. Verify it was printed properly by measuring the scale references on the first template.
Choosing the Right Printing Medium
By now, you will have noticed that this project requires a significant number of intricate cuts – and that is an understatement! Securing a pattern printed on regular paper with tape can be problematic here; if the template shifts during the cutting process, maintaining the necessary precision becomes impossible.
In these cases, sticker paper is often the best solution. However, its effectiveness depends entirely on the finish of your leather:
Oily/Waxy Leathers: if the surface is slightly oily, the adhesive will not bond too aggressively to the top grain. This is ideal, as the pattern remains secure during cutting but is easily removed afterwards.
Dry Veg-Tans: on very dry leather, standard sticker paper tends to bond too well. When you try to peel it off, the paper itself often tears apart, leaving the adhesive and paper backing stubbornly stuck to the grain. Trying to scrape this off can easily end in disaster.
Because the leather I used for the tower was on the dry side, I pivoted to a different solution: transparent sticker paper. This resolved the tearing issue, but introduced a new drawback: the adhesive was much stronger and risked damaging the top grain. I managed to mitigate this by “pre-sticking” the pieces to a clean bedsheet to weaken the adhesive before applying them to the leather. Even then, minor surface imperfections occurred. This was acceptable for the tower, as the paint layer would eventually hide any flaws, but it is something to keep in mind.
However, for the base, which I intended to dye rather than paint, I reverted to regular paper and masking tape to protect the grain.
In summary: experiment on a scrap piece first to find the method that works best for your specific leather. For the structural ribs, using white sticker paper is ideal. Since the cardboard will be hidden in the final assembly, the pattern can remain attached without any consequences.
Securing the pieces of the pattern on the leather
Roughly cut around each template element using an X-acto knife or a pair of scissors, leaving a small margin of paper around the edges.
Several structural elements are split across multiple pages. To prepare these, cut precisely along the dotted lines to reconstitute the full component.
Once your pieces are ready, secure them to the leather using the method appropriate for your chosen medium:
For sticker paper: align the individual parts directly on the leather surface. Remember to apply the adhesion-control techniques (such as the “bedsheet trick”) discussed in the previous section to ensure the pattern can be removed without damaging the grain.
For regular paper: join the split pieces with tape first, then secure the entire template to the leather using masking tape.
Punching the holes
Use your stitching prongs and hole punches to create all the holes indicated on the pattern.
If you have chosen to omit the support arches, do not punch the 2mm holes located on the first, second, and third-floor of the four facade elements.
Cutting out the pieces of the maquette
I’ve said it in the introduction, and I’ll say it again: using a laser cutter is highly recommended for this project. However, if you have decided that you are up for the challenge, here is how all those tiny architectural features can be cut by hand.
I used a combination of X-Acto blades to complete the work. The most critical tools were a 5mm straight blade and a 2mm straight blade, the latter of which I created by grinding down a standard slanted blade with a rotary tool. These straight blades are essential for cleanly and easily cutting the small triangles; by pressing directly down into the leather, you avoid the “drag” of a slanted blade, which often results in skewed or overshot cuts.
In most cases, however, the corners require a small amount of assistance to fully free the triangle. This is where a small slanted blade excels, allowing you to precisely clear out any remaining uncut fibers.
The 2mm straight blade is also particularly useful for cutting the slots in the structural ribs.
Once all the internal features of the maquette components have been removed, take a moment to celebrate your progress – then proceed to cut out the elements themselves.
The support arches for the different levels are very similar in appearance. To avoid confusion or loss, keep them separated and labelled immediately after they are cut.
(I have included a few spares in the template just in case.)
Bevelling and skiving
Bevel the side edges of the following elements on the flesh side to facilitate easier assembly:
Tower facades
First floor inner galleries
Vaults of the cupola
Base facades of the cupola
Third floor railings
Second floor railings
First floor outer balustrade
First floor inner gallery
All pedestal sides
For the base components, bevel both sides of the vertical edges on the side panels (excluding the top and bottom edges). For the base top and base bottom, bevel both sides of all four edges. After dyeing, burnish these newly bevelled edges to a smooth finish.
Skive all four tabs of the cupola antenna holder. Reducing the thickness of these tabs will significantly facilitate the stitching process for this component later on.
Hardening the leather
Cutting out that much material from the facade makes the leather very flexible, which is definitely not something we want for a 60cm tall maquette. We need to find a way to harden the leather to ensure we don’t end up with Expedition 33’s floppy Eiffel Tower.
This is a whole topic in and of itself. During my research, I found a video from Weaver Leather Supply where they introduce different methods, including a product they sell. I’d recommend giving it a try if you are located in the US.
I am in France, however, so I purchased a hardener from Decocuir. I applied it to the flesh side, and while it did increase the firmness slightly, I felt it was not sufficient. After reading through a comparison of 16 different leather hardening methods and experimenting myself, I settled on this protocol: immerse the pieces in 95% rubbing alcohol, let them dry, and then apply the hardener from Decocuir on the flesh side with a high-density sponge brush. One coat is enough, as it then seals the fibres and prevents any further penetration of the product.
Preparing the LED strips and testing the electronics
About the electronics used in this project: When I began this project, I wanted to recreate the iconic light shows of the real Eiffel Tower. To achieve this, I settled on using controllable RGB fairy lights. If you have dabbled in lighting projects involving addressable LEDs, you will be familiar with the WS2812 protocol these strips utilize.
I chose the Gledopto controller because it offers an efficient way to manage both power and control logic. The WLED app provides a vast array of lighting options and animations, while xLights can be used from a computer to stream more complex sequences if desired. You can download my Celine Dion sequence here.
The circuit design is intentionally simple: one data line controls all four LED strips. This means each LED at the same vertical level across the four strips receives the same instruction. Since I did not plan on running animations that required addressing the strips independently, this was a perfect solution. Additionally, the LED ring at the top is daisy-chained to the output of one of the four strips, eliminating the need for extra wiring to run the length of the tower.
For the power input, I chose USB-C for its ubiquity and the ability to power the maquette from a power bank. However, one important note: depending on the cable and power supply used, the inexpensive panel-mount connector I sourced from AliExpress was capped at a 500mA output. Consequently, I limited the maximum system draw in the WLED app to 350mA. This prevents instability when the LEDs are at full white intensity, as the Gledopto controller and the power switch LED add their own load to the circuit.
Finally, I integrated a self-latching power switch with an integrated LED to add a touch of flair to the base and provide a tactile way to power the tower on and off.
To prepare the lighting, cut four strips of 22 LEDs each (assuming you are using strips with one LED every 15mm). Do not cut the wires flush with the LED; leave as much exposed wire as possible on both ends.
If you are using a different type of LED strip, cut the sections so that their length matches the side of the tower’s facade. Pay special attention to the first and second floors: position your strips so that a wire section aligns with the level’s floor, rather than an LED. The corners of the levels are notched to allow thin wires to thread through, but an LED will be too large to fit.
Next, prepare the following wiring:
Cut three 2cm sections of wire and strip both ends. These will be used to daisy chain one of the LED strips to the top LED ring.
Cut twelve 30cm sections of wire and strip both ends. These will connect the LED strips to the controller.
These clear wires are supplied as pairs. For two of the three required sections, keep the pairs intact. For the third section, separate a length of the paired wire to obtain the individual strands needed.
These LED strips are directional, featuring a distinct Data Input and Data Output end. It is essential to connect the correct end to the controller; ensure you have identified the direction of flow and mark the input end with a black marker for easy identification during soldering.
Solder three wires to each LED strip. Use heat-shrink tubing to insulate the individual connections and to bundle the wire groups together.
Note that one of the two wires in each pair is clearly identified by markings on its insulation. You must be consistent with which wire you connect to the positive and negative terminals of the strips so you can differentiate them when connecting to the controller. For the same reason, always solder the single “free” wire in the bundle to the data line.
Finally, use the 3cm sections to connect the output of one LED strip to the LED ring.
A note on wire choice: I initially used enamelled copper wire for these connections, thinking it would be more discreet. However, this proved to be a mistake. The connections were too brittle and broke during the stitching of the tower’s facades. I highly recommend using the same clear wires for these joints to ensure they are strong enough to withstand the assembly process.
Once the wiring is complete, test the entire circuit to ensure every component functions as intended. While the controller and its primary connections remain accessible in the base, the LED strips themselves will be stitched into the leather facades. Once the assembly is closed, you will no longer be able to repair or replace individual LEDs or their internal solder joints.
Perform a final “shake test” by gently moving the wires to ensure there are no intermittent connections before you begin the permanent stitching process.
Painting and dying the leather
I applied three coats of Angelus Bronze Metallic paint to all the tower components. For the primary surfaces, I used a high-density sponge brush to apply thin, even layers, while a small detail brush was used to reach the intricate nooks and crannies of the facade.
As noted in the introduction, using an airbrush would significantly accelerate this process.
To finish, I applied a single coat of Tan-Kote to protect the metallic pigment and enhance the tower’s characteristic shine.
To contrast with the metallic appearance of the tower and highlight the natural quality of the leather, I chose to dye the base using a blend of Hazelnut and Mahogany.
I applied the dye evenly with a high-density sponge. Once the dye had fully dried, I rehydrated the leather with Neatsfoot Oil to restore its suppleness before sealing the surface with a coat of Tan-Kote for a professional finish.
Assembling the maquette
Stitching techniques
Besides the cross-stitch and saddle stitch which are quite common in leathercraft, the tower requires two additional techniques which will be used to connect perpendicular pieces together.
I will refer to this first technique as the loop stitch. Only one needle is used. On the vertical piece, the result looks exactly like a standard saddle stitch.
The process begins by passing the needle through a hole in the vertical piece. On the horizontal piece, the thread enters the corresponding hole and loops around to return through that same starting hole on the vertical piece. You then move to the next hole and repeat the process.
This method secures the horizontal piece perpendicularly to the vertical piece, with its edge perfectly aligned with the stitching holes of the vertical piece.
I will refer to this technique as the double-needle loop stitch. Two needles on either end of the thread are used, beginning in two adjacent holes on the horizontal piece (first photo).
The first needle passes through the corresponding hole in the vertical piece (second photo), then through the opposite hole of the horizontal piece (third photo), and loops back through that same hole in the vertical piece. Finally, it passes back up through the hole in the horizontal piece (fourth photo), returning the needle to its starting position. From there, move through the next hole (where the second needle is located – fifth photo) and exit through the subsequent adjacent hole (sixth photo).
Repeat this process with the other needle (seventh photo).
While this technique can be achieved with a single needle, using two needles ensures that the straight stitch is not visually interrupted.
First floor
Use a loop stitch to join the four sides of the inner gallery to the deck of the first floor. Begin by back-stitching through a single hole to secure the start of the seam.
Once you reach the corners, secure the perpendicular edges with a cross-stitch. The only difference from a standard two-needle cross-stitch is the execution: the cross is completed by progressing upward in one diagonal direction and then returning downward in the opposite direction. This creates a cross-pattern on the interior and double-stitching on the exterior.
The facades slot through the notches located at each corner of the first floor’s deck. A relief cut at each corner allows the notch to open sufficiently to receive the facade.
Begin by fully inserting both ends of a single facade into the two corresponding notches on one side of the deck. Secure the piece by stitching one half of the facade in place using a double-needle loop stitch, stopping once you reach the corner.
Insert the next facade into the following edge of the deck.
At this point, the LED strip must be positioned. If using a strip with 15mm spacing, count eight LEDs below the first floor. Route the wires upward between the two facades and through the notch located at the inner corner of the deck.
Pay close attention to the orientation of the LED strip: ensure the LEDs face the interior of the tower to cast light inward, rather than toward the facade.
Once the LED strip is in place, close the relief cut with one cross-stitch – stitching between the two pairs of holes at the corner of the deck. Then, resume the double-needle loop stitch to secure half of the second facade to the deck.
Repeat this process at the three remaining corners to complete the assembly of the first floor.
Second floor
Unlike the first floor, the second floor is composed of two distinct elements: the deck, located inside the facades, and the promenade, which encircles them. The logic for stitching these elements together remains the same: use a double-needle loop stitch around the entire perimeter.
As you reach each corner, remember to route the LED strip through the notch in the deck. For this level, count nine LEDs below the second floor deck to ensure the spacing is correct.
Third floor
The process is identical to the second floor. The only specific detail to monitor is the orientation of the deck: ensure the notch is aligned with the same corner as the LED strip which is daisy-chained to the LED ring.
When you reach the notched corner, route the wires of the LED ring through the opening before stitching the next side.
Use double-sided tape to secure the ring firmly to the deck.
The facades
The corners of the facades are joined using a cross-stitch. If you have included the arches, the cross-pattern must be placed on the interior of the tower; otherwise, the thread volume will interfere with their seating. However, if you are not using arches, I recommend stitching the crosses on the exterior, as this provides much easier needle clearance during assembly.
The stitching holes are spaced 5mm apart, while the LEDs themselves are 10mm long. This means that every two holes, the stitch alignment corresponds with a section of wire between the LEDs. Secure these wire sections behind the thread as you stitch to effectively bind the LED strips to the tower structure.
Switching to curved needles for the upper section will make it easier to stitch that part.
Stitch all the way to the top and repeat the same process with the remaining corners to complete the tower structure.
Once the corners are stitched, the holes for the arches located at the corners beneath each floor tend to compress. Use a rotary tool with a 2mm drill bit to restore them to their proper diameter.
Before stitching the balustrades and railings, you can also use an awl or the tip of your hole punch to ensure that all the holes for the arches are sufficiently clear. The arches should be easy to insert, as the glue – rather than friction – will ultimately hold them in place.
Balustrade and railings
The first floor’s balustrade, as well as the second and third level’s railings, are all secured using the same loop stitch technique applied earlier to the inner gallery.
The first floor’s balustrade is stitched just like the inner gallery.
I found it more efficient to stitch the second floor’s railings using a curved needle. The defining feature of this section is the truncated corners, where a small railing segment is used to bridge the larger lateral sections.
The third floor’s railings combine structural elements from both the first and second levels: they feature truncated corners joined by a cross-stitch.
Cupola and antenna
The cupola consists of a dome with a circular opening at its apex. A specialized internal piece is stitched inside the dome to serve as a holder for the antenna.
Begin by joining two opposing pieces of the dome using a cross-stitch. Once you reach the apex, add a third segment and cross-stitch down the adjacent edge.
Repeat this process with the final quarter-segment to complete the dome structure.
The four components of the base facade are saddle-stitched to the lower perimeter of the dome.
At each corner, the two adjacent edges of the facade are joined using a cross-stitch. Simultaneously, secure one corner of the antenna holder as you pass that point with the saddle stitch.
The antenna is composed of three telescopic hollow brass sections with an acrylic rod running through the center. The dimensions for each section are as follows:
5mm brass section: 50.5mm
4mm brass section: 68mm
3mm brass section: 83mm
2mm acrylic rod and total length of the antenna: 88mm
The base of the acrylic rod sits directly on the LED at the center of the LED ring below. This rod functions as a light pipe, transmitting illumination to the apex of the antenna to mimic the signal light of the actual tower. To ensure the light is visible at the top, sand the tip of the acrylic rod until it becomesopaque, which helps to diffuse the light.
Once the rod is prepared, assemble the telescopic sections. Use a piece of tape to mark the precise point for the final cut. Use a rotary tool with a metal cutting disc to trim the antenna to its final height.
Finally, insert the antenna into the center of the cupola and secure it with super glue.
Pedestals
Each pedestal features a triangular profile, constructed from two smaller symmetrical segments joined by a longer section. Assemble the four pedestals by connecting these segments using a cross-stitch.
Support arches
To install the support arches, apply a small amount of adhesive into each hole using a toothpick or a precision applicator. Insert the two anchors of each arch into the prepared holes, ensuring they are fully seated.
I used Fiebing’s Leathercraft Cement for the arches located on the facades, as it provides a flexible, high-strength bond. For the corner arches, where the presence of the internal thread reduces the effective depth of the holes, I recommend using super glue. Its rapid curing time ensure these pieces remain secure despite the shallower mounting point.
Base
The structural ribs are engineered to prevent the upper section of the base from sagging under the weight of the tower, while providing essential reinforcement around the power button.
The area directly beneath the power button and in front of the USB port remains unobstructed; this allows these electronic components to be accessed or removed post-assembly in the event of a malfunction.
Clearance slots extending from each corner to the center facilitate the routing of the LED strip cables, ensuring they remain flush and do not protrude from the bottom of the structure.
Follow the assembly diagram to join the structural ribs by interlocking the corresponding segments. Ensure the printed letters on each piece are always facing upward to maintain the correct vertical orientation. As an additional visual guide for proper alignment, the clearance slots must always point downward. Furthermore, the clearance slot on any given segment will always correspond to a matching clearance slot on the perpendicularly interlocked piece.
Note that the internal structure is symmetrical; the right side mirrors the left side. Consequently, the components for the right side must be rotated 180° relative to their counterparts on the left to align correctly.
Next, stitch the top edge of the rear panel to the side of the base top located diametrically opposite the power button aperture – unless you prefer an alternative orientation for the USB port. Conclude this step by stitching down the vertical seam where the two adjacent side panels meet.
Continue by stitching the remaining side panels to the top of the base one after another until the perimeter is complete.
The service panel tabs are designed to secure the access panel to the underside of the base. Each tab houses the female component of a Chicago screw, providing a threaded anchor for the final assembly.
To secure the Chicago screw and prevent it from rotating during assembly, bond it to the tab using super glue. I used custom spacers created with 5mm and 7.5mm hole punches to ensure the Chicago screw sits flush with the surface of the tabs.
Once the adhesive has set, saddle stitch the five tabs around the perimeter of the access hatch on the bottom of the base, ensuring they are positioned on the flesh side of the leather.
The tower and the pedestals are secured to the base using their integrated triangular anchors. Use a pair of pliers to gently compress these anchors, reducing their profile until they are thin enough to pass through the corresponding slots at each corner of the base top.
Prepare these apertures by slightly enlarging them with the tip of a blunt tool, such as a wooden edge slicker. Once prepped, the anchors should slide into position with minimal resistance.
Slide a pedestal over each foot of the tower. The small leather strips that terminate the curve of each facade should extend outward from the pedestals.
Route the LED cables through the 5mm apertures at each corner of the base.
Begin the structural mounting by inserting the anchors of the tower’s feet into their corresponding slots in the base top. Using your pliers, unfold the tips of the anchors on the underside of the base to lock them in place.
Repeat this process for the pedestal anchors.
Position the structural ribs within the base, ensuring the interlocking segments are fully seated.
Next, install the push-button and the USB port into their respective apertures.
Ensure that the cables are routed through the dedicated notches at the base of the structural ribs. Use tape to temporarily secure them in position; this prevents the wiring from shifting out of the notches, which would otherwise create an unsightly protrusion on the leather at the bottom of the base. Once the cables are fixed, you may begin stitching the bottom panel.
Stitch the bottom panel to the side panels using a cross-stitch.
Secure the wire connectors and the LED controller to the underside of the access panel using double-sided tape. While I am using a black terminal block as a substitute, I strongly recommend using the specified connectors to simplify future maintenance or component replacement.
Begin the electrical assembly by connecting the controller to the wire connectors, using the circuit diagram as your primary guide. Next, route the wires from the USB port and the push-button to the 3-IN/6-OUT connector. Finally, attach the wiring from the tower LEDs to the 3-IN/12-OUT connector.
Conduct a thorough test of the electrical circuit to ensure all connections are secure and the LEDs function correctly before closing the access hatch.
Final touch
Only one step remains in this assembly: attaching the cupola to the top of the tower. This component is installed last to minimize the risk of damaging the delicate antenna during the extensive handling required to secure the tower to the base.
To permanently secure the cupola, apply super glue to the mounting surfaces. The base facade of the cupola is designed to slide over the protruding 5mm of the tower’s upper facades. This slip-fit design not only simplifies assembly compared to traditional stitching but also offers a functional advantage: if you opt for a replaceable lightbulb instead of integrated LEDs, the cupola can remain removable by omitting the adhesive.
Knowing the dedication and patience required to finish a project of this complexity, I sincerely congratulate you on reaching this milestone. You should be very proud of this achievement.

After reading through a comparison of 16 different leather hardening methods and experimenting myself, I settled on this protocol: immerse the pieces in 95% rubbing alcohol, let them dry, and then apply the hardener from Decocuir on the flesh side with a high-density sponge brush. One coat is enough, as it then seals the fibres and prevents any further penetration of the product.
Preparing the LED strips and testing the electronics
About the electronics used in this project: When I began this project, I wanted to recreate the iconic light shows of the real Eiffel Tower. To achieve this, I settled on using controllable RGB fairy lights. If you have dabbled in lighting projects involving addressable LEDs, you will be familiar with the WS2812 protocol these strips utilize.
I chose the Gledopto controller because it offers an efficient way to manage both power and control logic. The WLED app provides a vast array of lighting options and animations, while xLights can be used from a computer to stream more complex sequences if desired. You can download my Celine Dion sequence here.
The circuit design is intentionally simple: one data line controls all four LED strips. This means each LED at the same vertical level across the four strips receives the same instruction. Since I did not plan on running animations that required addressing the strips independently, this was a perfect solution. Additionally, the LED ring at the top is daisy-chained to the output of one of the four strips, eliminating the need for extra wiring to run the length of the tower.
For the power input, I chose USB-C for its ubiquity and the ability to power the maquette from a power bank. However, one important note: depending on the cable and power supply used, the inexpensive panel-mount connector I sourced from AliExpress was capped at a 500mA output. Consequently, I limited the maximum system draw in the WLED app to 350mA. This prevents instability when the LEDs are at full white intensity, as the Gledopto controller and the power switch LED add their own load to the circuit.
Finally, I integrated a self-latching power switch with an integrated LED to add a touch of flair to the base and provide a tactile way to power the tower on and off.
To prepare the lighting, cut four strips of 22 LEDs each (assuming you are using strips with one LED every 15mm). Do not cut the wires flush with the LED; leave as much exposed wire as possible on both ends.
If you are using a different type of LED strip, cut the sections so that their length matches the side of the tower’s facade. Pay special attention to the first and second floors: position your strips so that a wire section aligns with the level’s floor, rather than an LED. The corners of the levels are notched to allow thin wires to thread through, but an LED will be too large to fit.
Next, prepare the following wiring:
These clear wires are supplied as pairs. For two of the three required sections, keep the pairs intact. For the third section, separate a length of the paired wire to obtain the individual strands needed.
These LED strips are directional, featuring a distinct Data Input and Data Output end. It is essential to connect the correct end to the controller; ensure you have identified the direction of flow and mark the input end with a black marker for easy identification during soldering.
Solder three wires to each LED strip. Use heat-shrink tubing to insulate the individual connections and to bundle the wire groups together.
Note that one of the two wires in each pair is clearly identified by markings on its insulation. You must be consistent with which wire you connect to the positive and negative terminals of the strips so you can differentiate them when connecting to the controller. For the same reason, always solder the single “free” wire in the bundle to the data line.
Finally, use the 3cm sections to connect the output of one LED strip to the LED ring.
A note on wire choice: I initially used enamelled copper wire for these connections, thinking it would be more discreet. However, this proved to be a mistake. The connections were too brittle and broke during the stitching of the tower’s facades. I highly recommend using the same clear wires for these joints to ensure they are strong enough to withstand the assembly process.
Once the wiring is complete, test the entire circuit to ensure every component functions as intended. While the controller and its primary connections remain accessible in the base, the LED strips themselves will be stitched into the leather facades. Once the assembly is closed, you will no longer be able to repair or replace individual LEDs or their internal solder joints.
Perform a final “shake test” by gently moving the wires to ensure there are no intermittent connections before you begin the permanent stitching process.
Painting and dying the leather
I applied three coats of Angelus Bronze Metallic paint to all the tower components. For the primary surfaces, I used a high-density sponge brush to apply thin, even layers, while a small detail brush was used to reach the intricate nooks and crannies of the facade.
As noted in the introduction, using an airbrush would significantly accelerate this process.
To finish, I applied a single coat of Tan-Kote to protect the metallic pigment and enhance the tower’s characteristic shine.
To contrast with the metallic appearance of the tower and highlight the natural quality of the leather, I chose to dye the base using a blend of Hazelnut and Mahogany.
I applied the dye evenly with a high-density sponge. Once the dye had fully dried, I rehydrated the leather with Neatsfoot Oil to restore its suppleness before sealing the surface with a coat of Tan-Kote for a professional finish.
Assembling the maquette
Stitching techniques
Besides the cross-stitch and saddle stitch which are quite common in leathercraft, the tower requires two additional techniques which will be used to connect perpendicular pieces together.
I will refer to this first technique as the loop stitch. Only one needle is used. On the vertical piece, the result looks exactly like a standard saddle stitch.
The process begins by passing the needle through a hole in the vertical piece. On the horizontal piece, the thread enters the corresponding hole and loops around to return through that same starting hole on the vertical piece. You then move to the next hole and repeat the process.
This method secures the horizontal piece perpendicularly to the vertical piece, with its edge perfectly aligned with the stitching holes of the vertical piece.
I will refer to this technique as the double-needle loop stitch. Two needles on either end of the thread are used, beginning in two adjacent holes on the horizontal piece (first photo).
The first needle passes through the corresponding hole in the vertical piece (second photo), then through the opposite hole of the horizontal piece (third photo), and loops back through that same hole in the vertical piece. Finally, it passes back up through the hole in the horizontal piece (fourth photo), returning the needle to its starting position. From there, move through the next hole (where the second needle is located – fifth photo) and exit through the subsequent adjacent hole (sixth photo).
Repeat this process with the other needle (seventh photo).
While this technique can be achieved with a single needle, using two needles ensures that the straight stitch is not visually interrupted.
First floor
Use a loop stitch to join the four sides of the inner gallery to the deck of the first floor. Begin by back-stitching through a single hole to secure the start of the seam.
Once you reach the corners, secure the perpendicular edges with a cross-stitch. The only difference from a standard two-needle cross-stitch is the execution: the cross is completed by progressing upward in one diagonal direction and then returning downward in the opposite direction. This creates a cross-pattern on the interior and double-stitching on the exterior.
The facades slot through the notches located at each corner of the first floor’s deck. A relief cut at each corner allows the notch to open sufficiently to receive the facade.
Begin by fully inserting both ends of a single facade into the two corresponding notches on one side of the deck. Secure the piece by stitching one half of the facade in place using a double-needle loop stitch, stopping once you reach the corner.
Insert the next facade into the following edge of the deck.
At this point, the LED strip must be positioned. If using a strip with 15mm spacing, count eight LEDs below the first floor. Route the wires upward between the two facades and through the notch located at the inner corner of the deck.
Pay close attention to the orientation of the LED strip: ensure the LEDs face the interior of the tower to cast light inward, rather than toward the facade.
Once the LED strip is in place, close the relief cut with one cross-stitch – stitching between the two pairs of holes at the corner of the deck. Then, resume the double-needle loop stitch to secure half of the second facade to the deck.
Repeat this process at the three remaining corners to complete the assembly of the first floor.
Second floor
Unlike the first floor, the second floor is composed of two distinct elements: the deck, located inside the facades, and the promenade, which encircles them. The logic for stitching these elements together remains the same: use a double-needle loop stitch around the entire perimeter.
As you reach each corner, remember to route the LED strip through the notch in the deck. For this level, count nine LEDs below the second floor deck to ensure the spacing is correct.
Third floor
The process is identical to the second floor. The only specific detail to monitor is the orientation of the deck: ensure the notch is aligned with the same corner as the LED strip which is daisy-chained to the LED ring.
When you reach the notched corner, route the wires of the LED ring through the opening before stitching the next side.
Use double-sided tape to secure the ring firmly to the deck.
The facades
The corners of the facades are joined using a cross-stitch. If you have included the arches, the cross-pattern must be placed on the interior of the tower; otherwise, the thread volume will interfere with their seating. However, if you are not using arches, I recommend stitching the crosses on the exterior, as this provides much easier needle clearance during assembly.
The stitching holes are spaced 5mm apart, while the LEDs themselves are 10mm long. This means that every two holes, the stitch alignment corresponds with a section of wire between the LEDs. Secure these wire sections behind the thread as you stitch to effectively bind the LED strips to the tower structure.
Switching to curved needles for the upper section will make it easier to stitch that part.
Stitch all the way to the top and repeat the same process with the remaining corners to complete the tower structure.
Once the corners are stitched, the holes for the arches located at the corners beneath each floor tend to compress. Use a rotary tool with a 2mm drill bit to restore them to their proper diameter.
Before stitching the balustrades and railings, you can also use an awl or the tip of your hole punch to ensure that all the holes for the arches are sufficiently clear. The arches should be easy to insert, as the glue – rather than friction – will ultimately hold them in place.
Balustrade and railings
The first floor’s balustrade, as well as the second and third level’s railings, are all secured using the same loop stitch technique applied earlier to the inner gallery.
The first floor’s balustrade is stitched just like the inner gallery.
I found it more efficient to stitch the second floor’s railings using a curved needle. The defining feature of this section is the truncated corners, where a small railing segment is used to bridge the larger lateral sections.
The third floor’s railings combine structural elements from both the first and second levels: they feature truncated corners joined by a cross-stitch.
Cupola and antenna
The cupola consists of a dome with a circular opening at its apex. A specialized internal piece is stitched inside the dome to serve as a holder for the antenna.
Begin by joining two opposing pieces of the dome using a cross-stitch. Once you reach the apex, add a third segment and cross-stitch down the adjacent edge.
Repeat this process with the final quarter-segment to complete the dome structure.
The four components of the base facade are saddle-stitched to the lower perimeter of the dome.
At each corner, the two adjacent edges of the facade are joined using a cross-stitch. Simultaneously, secure one corner of the antenna holder as you pass that point with the saddle stitch.
The antenna is composed of three telescopic hollow brass sections with an acrylic rod running through the center. The dimensions for each section are as follows:
The base of the acrylic rod sits directly on the LED at the center of the LED ring below. This rod functions as a light pipe, transmitting illumination to the apex of the antenna to mimic the signal light of the actual tower. To ensure the light is visible at the top, sand the tip of the acrylic rod until it becomes opaque, which helps to diffuse the light.
Once the rod is prepared, assemble the telescopic sections. Use a piece of tape to mark the precise point for the final cut. Use a rotary tool with a metal cutting disc to trim the antenna to its final height.
Finally, insert the antenna into the center of the cupola and secure it with super glue.
Pedestals
Each pedestal features a triangular profile, constructed from two smaller symmetrical segments joined by a longer section. Assemble the four pedestals by connecting these segments using a cross-stitch.
Support arches
To install the support arches, apply a small amount of adhesive into each hole using a toothpick or a precision applicator. Insert the two anchors of each arch into the prepared holes, ensuring they are fully seated.
I used Fiebing’s Leathercraft Cement for the arches located on the facades, as it provides a flexible, high-strength bond. For the corner arches, where the presence of the internal thread reduces the effective depth of the holes, I recommend using super glue. Its rapid curing time ensure these pieces remain secure despite the shallower mounting point.
Base
The structural ribs are engineered to prevent the upper section of the base from sagging under the weight of the tower, while providing essential reinforcement around the power button.
The area directly beneath the power button and in front of the USB port remains unobstructed; this allows these electronic components to be accessed or removed post-assembly in the event of a malfunction.
Clearance slots extending from each corner to the center facilitate the routing of the LED strip cables, ensuring they remain flush and do not protrude from the bottom of the structure.
Follow the assembly diagram to join the structural ribs by interlocking the corresponding segments. Ensure the printed letters on each piece are always facing upward to maintain the correct vertical orientation. As an additional visual guide for proper alignment, the clearance slots must always point downward. Furthermore, the clearance slot on any given segment will always correspond to a matching clearance slot on the perpendicularly interlocked piece.
Note that the internal structure is symmetrical; the right side mirrors the left side. Consequently, the components for the right side must be rotated 180° relative to their counterparts on the left to align correctly.
Next, stitch the top edge of the rear panel to the side of the base top located diametrically opposite the power button aperture – unless you prefer an alternative orientation for the USB port. Conclude this step by stitching down the vertical seam where the two adjacent side panels meet.
Continue by stitching the remaining side panels to the top of the base one after another until the perimeter is complete.
The service panel tabs are designed to secure the access panel to the underside of the base. Each tab houses the female component of a Chicago screw, providing a threaded anchor for the final assembly.
To secure the Chicago screw and prevent it from rotating during assembly, bond it to the tab using super glue. I used custom spacers created with 5mm and 7.5mm hole punches to ensure the Chicago screw sits flush with the surface of the tabs.
Once the adhesive has set, saddle stitch the five tabs around the perimeter of the access hatch on the bottom of the base, ensuring they are positioned on the flesh side of the leather.
The tower and the pedestals are secured to the base using their integrated triangular anchors. Use a pair of pliers to gently compress these anchors, reducing their profile until they are thin enough to pass through the corresponding slots at each corner of the base top.
Prepare these apertures by slightly enlarging them with the tip of a blunt tool, such as a wooden edge slicker. Once prepped, the anchors should slide into position with minimal resistance.
Slide a pedestal over each foot of the tower. The small leather strips that terminate the curve of each facade should extend outward from the pedestals.
Route the LED cables through the 5mm apertures at each corner of the base.
Begin the structural mounting by inserting the anchors of the tower’s feet into their corresponding slots in the base top. Using your pliers, unfold the tips of the anchors on the underside of the base to lock them in place.
Repeat this process for the pedestal anchors.
Position the structural ribs within the base, ensuring the interlocking segments are fully seated.
Next, install the push-button and the USB port into their respective apertures.
Ensure that the cables are routed through the dedicated notches at the base of the structural ribs. Use tape to temporarily secure them in position; this prevents the wiring from shifting out of the notches, which would otherwise create an unsightly protrusion on the leather at the bottom of the base. Once the cables are fixed, you may begin stitching the bottom panel.
Stitch the bottom panel to the side panels using a cross-stitch.
Secure the wire connectors and the LED controller to the underside of the access panel using double-sided tape. While I am using a black terminal block as a substitute, I strongly recommend using the specified connectors to simplify future maintenance or component replacement.
Begin the electrical assembly by connecting the controller to the wire connectors, using the circuit diagram as your primary guide. Next, route the wires from the USB port and the push-button to the 3-IN/6-OUT connector. Finally, attach the wiring from the tower LEDs to the 3-IN/12-OUT connector.
Conduct a thorough test of the electrical circuit to ensure all connections are secure and the LEDs function correctly before closing the access hatch.
Final touch
Only one step remains in this assembly: attaching the cupola to the top of the tower. This component is installed last to minimize the risk of damaging the delicate antenna during the extensive handling required to secure the tower to the base.
To permanently secure the cupola, apply super glue to the mounting surfaces. The base facade of the cupola is designed to slide over the protruding 5mm of the tower’s upper facades. This slip-fit design not only simplifies assembly compared to traditional stitching but also offers a functional advantage: if you opt for a replaceable lightbulb instead of integrated LEDs, the cupola can remain removable by omitting the adhesive.
Knowing the dedication and patience required to finish a project of this complexity, I sincerely congratulate you on reaching this milestone. You should be very proud of this achievement.
