recycled t-shirt tote bag

Usually we post questions from you, our readers, and let everyone brainstorm away on them. Well, today I have a question for everyone! I am in charge of crafts at an overnight event for teen girls, so I need some craft ideas that can be made as a make and take at an event. I will have 100 to 200 girls stopping by over the course of a couple hours to make crafts with me. I need the crafts to be inexpensive, fairly quick (15-30 mins max), easy to explain, and appealing to girls 13-18.

I am thinking about doing the no-sew recycled t-shirt tote bag (pictured above).

We have gotten some great suggestions at our Facebook Page, but I want to see what else we can come up with!
