1. Download the pattern
Download the pattern and roughly cut out the pieces (with at least a 1 cm margin). Using masking tape (to avoid damaging the leather grain), tape the pattern pieces onto the full-thickness leather piece.
Roughly cut around the pieces, leaving about a 1 cm margin all around.
Cut a strip 1 cm wide by about 15 cm long from the split leather, as well as a 6x6 cm square for the covered snap button head.
2. Laminate the Salpa
Apply contact cement to the back of the main leather pieces (P1 and P2) and to the back of the Salpa.
Glue pieces P1 and P2 onto the Salpa and flatten everything with a roller.
3. Attach the snap button base
Punch a Ø3 mm hole in the center of piece P2.
Attach the snap button base. This step is done now so that the base is hidden by the lining.
4. Laminate with the lining
Apply contact cement to the back of the leather/Salpa pieces and to the back of the lining (pigskin or 0.5 mm thick leather - your choice).
 |
 |
Glue the pieces onto the lining, then flatten everything with a roller.
5. Trim the pieces
Using a utility knife, cut out pieces P1 and P2. Be careful to follow the dashed lines indicated on the pattern for the bottom of pieces P1 and P2. The bottom curves will be cut once the pieces are assembled for a more precise result.
We recommend cutting the outer curves in several passes => in sections (see video at step 10).
 |
 |
6. Work the edges
Sand the edges of the pieces that have just been cut. Then, apply an edge finish to the top of piece P2.
 |
 |
7. Topstitch P2
Create decorative topstitching on the top of piece P2 (on the part without dashed lines).
 |
 |
8. Prepare the tab P3
Take the small tab and fold it in half, inserting the snap hook. Glue the two sides together to hold the snap hook in place.
 |
 |
9. Assemble the case
Apply a 3 mm line of glue to the lining side (back) of pieces P1 and P2, along the dashed lines indicated on the pattern.
Glue the tab onto one of the two pieces, then glue the two pieces edge to edge.
 |
 |
10. Cut the curves
Once the pieces are well assembled and the glue is dry, cut the curves in sections (for a cleaner result - see video) following the black lines on the pattern.
11. Sew the case
Sew all around, about 3 mm from the edge.
It is also possible to hand-sew, with a simplified stitch or saddle stitch. Be careful to punch the sewing holes with a 1 mm diameter punch at step 5.
Or simply fasten the two parts with T3 rivets. The locations for the Ø 3 mm holes are marked on the pattern.
 |
 |
12. Sand and finish the edges
Sand the edges again, then apply an edge finish.
13. Attach the snap button head
Finally, attach the snap button head. We covered the button with 0.5 mm thick leather.

OLD VERSION
MATERIALS NEEDED
To complete this tutorial, you will need:
- 1 piece of leather 20x30 cm - Thickness between 1.2 and 1.5 mm - Rather firm leather
- 1 D-ring - 10x10x2 mm
- 1 mini swivel snap hook diam 9 mm OR 1 round snap hook
- 1 nickel-plated snap button - diam. 10.5 mm OR 1 collar button
- Leather glue
- Edge finish - Colorcut - 30ml
- Tokonole
- 4 nickel-plated T3 rivets (stitch-free version only)
- 1 spool of polyester thread N°30 - Chocolate (stitched version only)
- 1 strap of collar leather. Width: 10mm - Length: 120 cm (optional)
And the following tools:
- Accessory setting tool and dies
- 1 round punch - Ø 3 mm
- 1 mallet
- 1 silver pen
- 1 pair of scissors
- 1 fine abrasive sponge - 400 grit
1. Cut the leather using the pattern
Download the leather glasses case pattern and print it to actual size. Cut it out, remembering to make the holes using the 3 mm punch. Trace the pattern onto the leather piece with a silver pen and cut out the 3 pieces with a pair of sewing scissors or a utility knife (depending on your leather).
We advise you to cut/work the rounded sides once the pieces are assembled.
Simplified sewing version: punch sewing holes with a punch of maximum 1 mm diameter.
Do you own a Cricut? Download the pattern (sewing version) in SVG at the top of the page. Be careful to resize the shape correctly in the Cricut software. It should be 26.8 cm wide and 22.4 cm high.
2. APPLY TOKONOLE
Apply tokonole to the flesh side of the leather to give it a smooth, shiny appearance and to prevent lint from getting on sunglasses. 
3. START EDGE DYEING
Before assembly, work the edges of the small tab, the large tab, and the top of piece #3 (the part that will not be assembled with the other pieces). Dye the edges with leather paint (see material list).
4. ASSEMBLE PIECES #1 AND #2
Fold and glue the small tab of piece #1, inserting the D-ring or snap hook.
Apply leather glue to the flesh side of pieces #1 and #2. Wait a few moments then laminate the pieces.
5. DO DECORATIVE STITCHING (VERSION 1 ONLY)
For the sewn version, make a decorative stitch on the large tab and the top of piece #3.
6. FINISH ASSEMBLING THE PIECES
Apply a thin layer of glue to the edge of the main piece and piece #3 and assemble the pieces.
7. SEW THE PIECES TOGETHER OR ATTACH RIVETS
Riveted version: attach T3 rivets as indicated on the pattern to hold the layers together.
Sewn version: sew the pieces together.
Simplified sewing version: To start, cut a thread 5 times the length of the stitching line. Then, thread a needle through each end of the thread. Sew the two pieces together by passing each needle through each hole. Make 3 backstitches.
To finish the seam, cut the thread flush and apply a dot of glue. Then tap the seams.
8. WORK THE EDGES
To better work the curves and have a uniform edge: sand the edges (always in the same direction) with an abrasive sponge or 400-grit sandpaper.
Apply finish to the edges of the case. Then sand with the abrasive sponge and apply a second coat. If necessary, apply a third coat.
9. ATTACH THE SNAP BUTTON OR COLLAR BUTTON
Attach the snap button using a setting tool (the head on the tab and the foot on piece #3).
VIDEO: HOW TO ATTACH A SNAP BUTTON >
You can choose to close your case with a collar button.
To do this, make a 3 mm diameter hole through the 3 layers of leather and then screw in the collar button.
10. OPTION: PREPARE A STRAP
If you want to wear your glasses case around your neck, make a leather strap. Make 3 holes of 3 mm in the strap, pass the snap hook through, and close the strap with a rivet.
All that's left is to attach the snap hook to the case! It's also possible to reverse the snap hook and the D-ring so you can attach your glasses case to a belt, a handbag, etc. 
Your glasses case is finished
Ready to go with you everywhere!
Here are other examples of creations:
Case made without stitching, with rivets. Can be hung around the neck with a chain or on a handbag.

The cases below were made using the sewn version. We used round snap hooks to easily attach the case to a belt.

Bonjour, est-il est possible d’ajouter le patron cricut (svg) de la version “couture simplifiée”. Le SVG actuel ne propose que la version “avec couture” dont la partie découpée s’arrête plus bas (avant le bas du mousqueton). J’aurai aimé avoir celui qu’on reçoit avec le tutoriel du kit. Merci d’avance.
