Position the longer shoe shelf board horizontally on top of the two vertical side boards with the side boards either at the ends of the shelf or evenly spaced in the middle of the shelf board. Predrill two holes down through the top of the shoe shelf board into the side boards, drilling just the shelf board; drill the side boards if necessary to ensure proper alignment of the two pieces.
Attach the pieces together with wood screws, drilling completely into the wood until the screw heads are flush with the shelf board surface to prevent shoes from catching on them.
Repeat this process for additional levels of shoe storage, stacking as many shelves as necessary on top to provide adequate organization.
Locate the studs in the desired section of the wall using the stud finder. Mark their location with a pencil, and measure the distance between the centers of the studs with the measuring tape. Make two markings on the front surface of the coat rack board, evenly spaced the same distance apart as the studs.
Attach the coat hooks evenly across the front of the board, allowing plenty of space for bulky coats if necessary. Use the hardware provided with the hooks, or simply attach them to the board using wood screws.
Hold the coat rack against the wall and line up the previous markings with the stud position markings. Set the carpenter's level on top of the rack to make sure that it is level. Predrill holes into the wall through the coat rack. Attach the coat rack to the wall using wood screws.
