The inside wall above a garage door makes a good storage space. Use this area to store long pieces of wood molding, dimension lumber, or plumbing pipe. Attach metal or wooden support brackets to the sleeper studs or header. Metal brackets available at any hardware store or home center can be attached to the front of sleeper studs with long wallboard screws or lag screws. Or cut L-shaped wooden brackets from scrap plywood and attach them to the sides of the sleeper studs with 2" wallboard screws. To provide adequate support, space the brackets no more than 36" apart.
