This is a Diaper Clutch. It only holds a few diapers and a couple of wipes so if you have to run a quick errand, you can grab this and go. No need to take the BIG diaper bag. There is a tutorial here. I made mine a little more simply, I just used solid black quilted material and trimmed it with patterned material. A friend is expecting this will be her gift. Here are a few close-ups:
In this picture I put 4 - size 4 diapers inside. Thanks for looking!
