1. CUT THE LEATHER USING THE PATTERN
Transfer the pattern to the leather using a silver pencil. Pay attention to the positioning of the pattern on the leather to have a direction of opening of the case on the left or on the right.
Cut the leather with a cutter.
Coarsely cut the curves, they will be cut more cleanly when assembling. 
2. GLUE THE FLAP
Glue the flap to the rounded part of the main piece. 
3. SEW THE KEYCHAIN CASE
Sew a seam all around the piece. Carefully follow the rounded line made in silver pencil (flap). 
4. CUT THE ROUND
Cut the excess leather with a cutter following the curve. 
5. WORK THE CASE SLOTS
Sand the edges of the case (always in the same direction) with an abrasive sponge. 
Apply dye to the edges of the case. Then sand with the abrasive sponge and apply a second coat. If necessary, apply a third coat. 
6. ATTACH THE RECTANGULAR LOOP
Make the holes using knockout punches and a mallet. Then place the rectangular loop in the tongue and rivet. 
7. INSTALL THE SNAP BUTTON
