I made this simple small coin purse or card case out of a dark brown cowhide leather. The stitching was done by machine with a yellow thread. It has a traditional snap closure. I left the edge of the closing flap as the natural edge the the leather had as I liked that more natural organic feel to it.
Measures approx 3" by 3 3/4" with the card area being about 2 1/2" by 3 1/2". I can easily fit two credit cards in here. So it's great for your ID and debit card or use it for change.
