RECTANGLE KIT VERSION
NECESSARY MATERIAL
Final dimensions of the kit (if piece of 25x25 cm): 17 x 7.5 x 7 cm
To make the leather case you need:
- 1 piece of soft leather measuring 30x40 cm in the color of your choice – thickness between 0.8 and 1.4 mm. In the models below we have selected a piece of Satinlys leather 0.8 mm thick (because the leather is firm).
- 1 30 cm zipper (spiral or plastic closure)
- 1 silver pencil
- 1 metal ruler
- 1 cutting mat
- 1 cutter and scissors
- 1 sewing machine (which accepts thicknesses)
- Polyester thread n°30 in the color of your choice
Little extra: don't hesitate to line your leather case with a fabric lining (we recommend coated fabric to avoid having fabric that frays) , alcantara or pigskin leather.
1. CUT THE PIECE
- Using the silver pencil, trace a 25 x 25 cm square on the leather.
- Cut out the pattern using a square and a cutter.
- Trace and cut a 2 x 5 cm strip
If you choose to line the kit: also cut a 25x25 cm square from the lining of your choice.
The pencil can be erased on most leathers with a simple eraser (do not use on vegetable tanned leather). We advise you to do a test beforehand to validate the erasable function on your leather.
Adapt the size of your piece of leather to have the kit that suits you! 
2. SEW THE ZIPPER
Open the zipper and position it on one end of the main piece with pliers or adhesive tape (starting side of the slider).
Sew the zipper onto the leather (use the zipper presser foot). Do not make the stitches too tight as this could stretch the leather.

Then place the other part of the closure (still on the starting side of the slider) on the lower end of the leather and sew. Be careful that the closure is not in the wrong direction.

For the option with the coated fabric lining:
- Position the lining flat, right side towards you. Then place the zipper on the longest side of the lining (right side towards you and against the edge). Finally, place the piece of leather on the zipper to sandwich it (with the wrong side towards you).
Use double-sided tape or sewing clips to hold the pieces and sew them with the zipper foot.
Sew the other side with the fabric lining, proceed in the same way as in the previous step. Please note: we advise you to select a separable zipper to make sewing this part easier. 
Then, turn the whole thing over from the center and make the last topstitch 2 mm from the edge.
3. SEW THE WIDTH OF THE KIT
Turn the leather over, the right side should be inside and the zipper in the center.
Close the zipper, leaving a small opening so you can turn the case over at the end. 
Place the tab (folded in two inwards - use double-sided tape) between the two layers of leather at the level of the zipper slider. It is possible to put a tab on both sides of the kit
Sew on each side of the pencil case widthwise.

4. CUT THE CLOSURE
After sewing, cut and burn the excess ends of the zipper.
For the option with fabric lining, we advise you to also make a zig zag stitch on each side of your pencil case.
5. DRAW LINES 3 CM FROM EACH EDGE
Using the silver pencil: draw lines of 4 cm to 3 cm from each edge of the case (on the front and back: 8 lines in total) - valid for a 25x25cm case.
If you have opted for a 20x25 cm rectangle we recommend making a line of 3 cm 2 cm from each edge.
6. FORM THE CORNERS OF THE KIT
Lay the kit flat and form the corners, each line must join that of the other side.
Hold the corners with sewing clips. 
7. SEW AND CUT CORNERS
Sew the corners following the lines drawn with a silver pencil. 
Then cut the corners 1 cm from the seam.
For the option with fabric lining, we advise you to make small bias bindings (4 squares of 4x4 cm whose edges have been folded) and position them, with double sided, on each cut side. 
Make a zig zag stitch to maintain the bias. 
The final result will be even prettier! 
8. RETURN THE KIT
Open the leather case completely and turn it over.
Final dimensions of the kit: 8.5 x 19 cm.

1. CUT OUT THE PATTERN PIECES
Download the pattern and print it in full size (download in the tab at the top of the page). Cut the 3 pattern pieces and trace them on the back of the leather (crust side) using a pencil. Part P2 must be traced twice. Then cut the leather with a pair of scissors. 
2. SEW THE ZIPPER
Place double-sided, crust side, on one of the lengths of the large rectangle (one of the 18 cm sides). Center the edge of the leather on the zipper 5 mm from the spirals. Then sew the zipper with a closing presser foot. 
3. SEW THE ZIPPER AND TRI-COLOR RIBBON
Put double-sided tape on the other length of the large rectangle and stick it on the other side of the zipper. Cut 2 cm of tricolor ribbon, fold it in 2 and wedge it between the leather and the closure. Open the zipper completely and sew 3 mm from the edge. 
4. GLUE THE SIDES
Turn the case over and close the zipper, leaving an opening so that you can open the case after sewing. Put double-sided tape on the right side (flower side) of the 2 circles and fold the small tab (P3) in 2. Glue the circles edge to edge on each side of the case, inserting them flower side inside.
