I just finished a small card/money holder for a friend at work.
Here is a picture of the inside opened up. It just folds up.
And here is a closer look at the pockets. Hard to see with the black fabric. I had made her a special order Betty Boop purse for her daughter-in-law for Christmas. She liked it so well, that she requested a card holder (for credit cards, ID etc). I added a red snap to give it a little color variation.
