Flip-through tool storage. Plywood “leaves” swing from standard door hinges, allowing quick and easy access to tools. Wall space is always at a premium. Build this booklike storage rack, and expand your wall space exponentially. Grabbing a tool is as easy as flipping through a magazine. Mount two parallel 2x4s on the wall spaced 24 in. apart. Cut the leaves from 3/4-in. plywood and hang them from the 2x4s with 3-in. door hinges.
