I'm a novice at leaherwork, carving and tooling, having made a few wallets, belts, and such for myself and family. My grandson has asked me to make him a custom wallet with something "cool" on it. At age 12, I know he wouldn't want want a bulky wallet, he want's something rather thin. So, I'm thinking of something simple, stitched rather than laced, so that it will fold and be rather flat. Which weight leather would be a good ballance between weight (thickness) and strength and wearability? I want a quality leather that will last, but something that will also carve and tool. I know I have to be careful carving thin leather. What are recommendations? Also, where could I buy just enough for a few wallets, not a whole side? I welcome any advice whatsoever.
