A nice, fairly simple, DIY project building shelving from dimensional lumber. Quick and easy shelves for garage, basement, or workshop. One note I would like to add is to be sure to use either structural screws or lag screws for the framing of the shelves, and attachment to the wall. Drywall screws and deck screws (most deck screws) do not provide sufficient shear strength to support heavy loads. For attaching the plywood, deck screws would be sufficient, as there is no shear load.
