Great thread!
Here's a cordovan wallet/card case I made under the guise of a design project started with some friends. To make a long story short, I lived abroad for a little while and my wallet went on a major diet. I got used to a pared down wallet and when I got back to the states, I designed a few concepts that focused on compartmentalization in a small footprint.
Being a huge fan of Horween Cordovan and also some of the leathers other tanneries churn out, it was easy to decide on what to use. However the biggest challenge was making sure the wallet didn't turn out too thick but the finished product was just about perfect dimensionally, for me at least. It holds about 4-5 cards, and 6-8 folded bills. Three compartments, (2 for cards in front, 1 in mid) and 1 compartment in the back for cash.
Sorry for the low quality pics but you can kind of get the idea. It's made using Horween black cordovan, about 4 to 5 oz on average and linen thread.



I can carry this in my front, back or even jacket pocket if I'm wearing a suit. And it's cordovan so my jacket pocket has a hint of cordovan scent now
