It's made of relatively thin leather and is glued and hand-stiched. I designed to be really thin in the pocket and still be able to hold a decent amount of cards and backup cash. Coins go in my pocket on the rare occasions I use cash and get change back. I'm thinking about making more of them and selling them.
Looks nice! I have just started in leatherworks. Looking at the bill I guess you are from Sweden? Any good sources for leather here except slöjddetaljer? It's not failure if you learn something from it
