Great phone wallet design - would be easy enough to duplicate. I would eliminate the binding (since mine would be a mess, lol) and just sew a backing on RST. The zipper pouch could be the kind from Michelle Patterns Zip Pocket Pouch.
LOVE THE HANDLES DIY Canvas Bag! This is a great How to on how to make a simple carry all. Use your fabric materials such as velvet, flannel, felt or burlap to make your own two tone bag. Just thought this was cool!
