Ok, so this tutorial describes how to turn a regular unshrunk wool sweater into a nifty backpack with some purposeful alterations, but the same principle can be used to reappropriate your tiny knits.
You're going to need:
- An industrial zipper. You can pick these up in some fabric supply stores, you might also consider going to a car upholstery shop (as I did) and finding out where they get their zippers.
- A 100% wool sweater. I found two for three bucks each at the local Salvation Army.
- A washing machine. You're going to need to tumble this in the washing machine on hot, with a little dish detergent added to get it to felt. Some tutorials I've read recommended putting it inside of a pillow case to prevent fuzz from clogging up your washer.
- A sewing machine with thread to match or accent your sweater.
