Don't throw away old T-shirts and shorts, sew a rug! A soft, bright rug made from old T-shirts and other cotton jersey clothing is perfect for an entryway or bathroom. If you show patience, you can sew a larger rug for the children's room. You can make not only a striped rug, but also colored squares or with an intersting pattern.
