I made a new wallet for myself today. This wallet corrects two major flaws of the first wallet I made: My cards don't fall out and Maggie can't open it. Also it is much cuter.
I followed this tutorial (PDF warning) except that I didn't do a vinyl pocket and a keyring and I used a sew-on snap. The lining on the wallet is the same as the lining on the old wallet and on my purse.
