You can make a simple peg loom out of drinking straws and yarn. Take a few straws, cut a small notch near the bottom of each, and thread a strand of yarn through each. Tie each doubled strand near the bottom and begin wrapping a new strand around each straw. There are tutorials on straw loom weaving if you search for it.

My niece made this headband in less than 30 minutes with only four straws and a small amount of self-striping yarn. Talk about a DIY craft! If you are having a headband emergency–and don't we all–this is definitely a colorful, creative and frugal solution.
