There are several at the Moda Bake Shop. I'm planning to make the one below for my granddaughter. It's a gift bag so it will be small enough for a one year old.

I also have a pattern from JoAnn for a bag made from a denim pocket. But I don't have the link for that one. You could search the Joann.com website.
