Note: A total of nine sheets of 4' x 8' birch plywood were used in this demonstration; shelf dimensions will vary according to the size of your space.
Locate and mark studs in the wall, then pre-drill the shelves at the corresponding measurements of the stud locations.
Mount first shelf to the wall and secure screws into the studs. A telescoping painter's pole like the one shown in the image can assist in supporting the shelf during installation.
Attach vertical risers onto the first shelf, then drill up through the riser from bottom surface of first shelf to secure.
Slide the second shelf onto the risers to rest on the riser pins. Place the third shelf onto the top of the vertical risers and screw it into place into the risers.
Attach the second and third shelves to the wall by securing 3" wood screws in the pre-drilled holes.
