Becky from Sew and So shares a tutorial for making a fabric wallet. Inside the wallet are pockets (6 of them) to hold credit cards, ID, or maybe folded money. The edges are finished with contrast binding, and a tab wraps around for the closure. She used a large snap, but you could also use Velcro or magnetic snaps or a button. Go to Sew and So for the tutorial.
