Decided to try a wallet with a coin pocket and turned edges on the pockets. Didn’t quite come out as I planned; the turned edges made the sides a bit more bulky and it could have been a bit neater but it was a learning experience. I would definitely use a firmer leather on the inside next time that would be easier to edge and skive.
@mt63 That's a great attempt for a first time! I'm glad to see you trying new things.
