I have cut up and used clothing for quilts. As long as the material is still good why not? I made a pair of beautiful throw pillows for my daughter out of an jacket that was made from a taprestry type material. I always take off all the buttons from used clothing. My grandmother used to make me clothes from men's suits she bought at rummage sales. She always saved the buttons and zippers. In these economic times perhaps we could all take a lesson in reusing items instead of throwing them away.
