My wife makes hand made bags, she's volunteered to make a few for me to give away at burning man. They have a zipper, and an open pouch on the front. The bag's are sewn so they have room, on either side of the front pouch for sharpie sized pens(though as they are sealed on three sides, and long thin object that's thinner will also fit. I use mine for my electronic cigarettes.)
I obviously wouldn't have enough to be handing them to just anyone, but if someone commented on liking my bag, I'd be able to give them to those that want it. They roll up really small as they have no stiff walls. I'm thinking about attaching a BM2014 shrinkydink key chain to each. I throw mine over my neck like an oversized badge holder, but they can easily be carried as purses as well given the length of the strap.
Anyone foresee any problems with this that I don't?
