Then I found http://www.campusquilt.com/. It's so easy! You place the order and they send you a kit to package all your t-shirts and in 3-4 weeks you have an awesome quilt made from your old t-shirts. I don't have any before pictures, but hopefully in a few weeks you can see the finished product!
What would you make a quilt out of? They can add picture squares (too cool) and make quilts out of baby clothes. It's a pretty cool idea, check it out!
