1. Download the pattern
Download the pattern and cut out the pieces roughly (at least 1 cm margin). Using masking tape (to avoid damaging the grain of the leather) , stick the pattern pieces to the full-thickness piece of leather.
Roughly cut around the pieces, leaving about 1 cm margin all around.
Cut a 1 cm wide and approximately 15 cm long strip from the split leather, as well as a 6 x 6 cm square for the head of the covered snap fastener.
2. Lay the Salpa
Apply contact glue to the back of the main leather pieces (P1 and P2) as well as to the back of the Salpa.
Glue parts P1 and P2 onto the salpa and flatten the assembly using a pressure roller.
3. Place the press stud foot
Drill a Ø3 mm hole in the center of part P2.
Place the press stud foot. This is done at this stage so that the foot is hidden in the lining.
4. Lay down with the lining
Apply contact glue to the back of the leather/Salpa pieces as well as to the back of the lining ( pigskin or 0.5 mm thick leather - your choice) .
 |
 |
Glue the pieces onto the lining, then flatten the whole thing with a pressure roller.
5. Overcut the pieces
Using a cutter, cut out pieces P1 and P2. Be sure to follow the dotted lines indicated on the pattern for the bottom of pieces P1 and P2. The rounded edges at the bottom will be cut out once the pieces are assembled for a more precise result.
We recommend cutting the external roundings in several times => into quarters (see the video at step 10).
 |
 |
6. Work the slices
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
Make a decorative topstitch on the top of piece P2 (on the part without the dotted lines).
 |
 |
8. Prepare the P3 tab
Take the small tab and fold it in half, inserting the carabiner. Glue the two sides together to hold the carabiner.
 |
 |
9. Assemble the case
Apply a 3 mm bead of glue to the lining part (the back) of pieces P1 and P2, at the dotted lines indicated on the pattern.
Glue the tab to one of the two pieces, then glue the two pieces together edge to edge.
 |
 |
10. Cut out the curves
Once the pieces are well assembled and the glue is dry, cut the curves into quarters (for a cleaner result - see video) following the black lines of the pattern.
11. Sew the case
Sew all around about 3 mm from the edge.
It is also possible to sew by hand, using a simplified stitch or a saddle stitch. Be sure to pierce the stitching holes with a 1 mm diameter punch in step 5.
Or simply attach the two parts using T3 rivets. The locations of the Ø 3 mm holes are marked on the template.
 |
 |
12. Sand and work the slices
Sand the edges again and then apply an edge finish.
 |
 |
13. Place the head of the snap fastener
Finally, place the head of the snap fastener. We covered the button with 0.5 mm thick leather.

OLD VERSION
THE NECESSARY MATERIALS
To complete this tutorial, you will need:
- 1 piece of leather 20x30 cm - Thickness between 1.2 and 1.5 mm - Fairly firm leather
- 1 half-round ring - 10x10x2 mm
- 1 mini round carabiner, diameter 9 mm OR 1 round carabiner
- 1 nickel-plated snap fastener - diam. 10.5 mm OR 1 collar button
- Leather glue
- Edge Finish - Colorcut - 30ml
- Tokonole
- 4 T3 nickel-plated rivets (seamless version only)
- 1 spool of polyester thread No. 30 - Chocolate (sewing version only)
- 1 leather collar strap. Width: 10mm - Length: 120cm (optional)
And the following material:
- Tool and sets for installing accessories
- 1 round punch cutter - Ø 3 mm
- 1 mallet
- 1 silver pencil
- 1 pair of scissors
- 1 fine abrasive sponge - grain 400
1. Cut out the leather using the template
Download the leather glasses case pattern and print it in actual size. Cut it out, remembering to make the holes using the 3 mm punch. Transfer the pattern onto the piece of leather using a silver pencil and cut out the 3 pieces with a pair of sewing scissors or a cutter (depending on your leather).
We recommend cutting/working the rounded sides when the pieces are assembled.
Simplified sewing version: pierce the sewing holes with a punch with a maximum diameter of 1 mm.
Do you have a Cricut? Download the pattern (sewing version) in SVG at the top of the page. Be sure to resize the shape in the Cricut software. It should be 26.8 cm wide and 22.4 cm high.
2. APPLY TOKONOLE
Apply tokonole to the crust part of the leather to give it a smooth and shiny appearance and to prevent lint on sunglasses. 
3. START SLICE DYEING
Before assembly, work the edges of the small tab, the large tab and the top of part #3 (the part that will not be assembled with the other parts). Tint the edges with leather paint (see the materials list) . 
4. ASSEMBLE PARTS NO. 1 AND NO. 2
Fold down and glue the small tab of part no. 1, inserting the half-round ring or carabiner. 
Apply leather glue to the furry side of pieces 1 and 2. Wait a few moments then glue the pieces together. 
5. MAKE THE DECORATIVE SEAMS ( VERSION 1 ONLY)
For the version with stitching, make a decorative stitch on the large tab and the top of piece no. 3. 
6. FINISH ASSEMBLING THE PARTS
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 INSTALL RIVETS
Version with rivets : place T3 rivets as indicated on the pattern to hold the thicknesses together.
Sewing version : sew the pieces together. 
Simplified sewing version : To begin, cut a thread equivalent to 5 times the length of the stitching line. Then, thread a needle through each end of the thread. Sew the two pieces together, passing each needle through each hole. Make 3 backstitching stitches.
To finish the seam, cut the thread flush and apply a dot of glue. Then tack the seams.
8. WORK THE SLICES
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 the 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. INSTALL THE SNAP BUTTON OR COLLAR BUTTON
Install the pressure button using an installation tool ( the head on the tab and the foot on part no. 3) .
VIDEO: HOW TO INSTALL A SNAP BUTTON >
You can choose to close your case with a collar button.
To do this, make a 3 mm diameter hole that goes through the 3 thicknesses of the 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 three 3mm holes in the strap, insert the carabiner, and fasten the strap with a rivet. 
All that's left is to attach the carabiner to the case! It's also possible to reverse the carabiner and the half-round ring so you can attach your glasses case to a belt, handbag, etc. 
Your glasses case is finished
Ready to accompany you everywhere! 
Here are some other examples of achievement:
Seamless case with rivets. Can be hung around the neck with a chain or on a handbag .
Leather from the PETIT GRAIN CAVIAR range

The cases below were made in the stitched version. We added round carabiners to easily attach the case to your 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.
