Repurposed cardboard, y’all.

Additional proof that you can make clothes from, well, just about anything? Check out these items made from Golden books, book pages, computer wires, shirt collars, t-shirts, dry cleaner bags, a parachute, bicycle tire inner tubes, Starburst candy wrappers, plastic shower curtains, and a FEMA tarp. Whew!
