I have a conventional wallet. It's great for credit cards, cash, receipts. Not so great for change. First, I have to dump out all the change in my hand to be able to see what's in there: the little zippered opening is just too small. With this bag, I set out to make the change purse I want to carry myself. It's great. And it is the sort of perfect for just about anyone change purse that you can knit almost in 15 minutes - I got really fast when I had to make a whole bowl full of them. i finished them in a blink.
