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. Fur out the hinges with 3/4-in. plywood blocks so the pages can pivot without binding. Mount the leaves at least 4 in. apart to allow room for them to fold back. Let your imagination run wild creating holders for your various tools.
