Step 5: Constructing support structures
Doing some basic math for the "studs". I want the shelf to be at 26'' therefore, 26" - 3" (top and bottom plates) = 23" <--- this will be the cut for the studs. Cut two per structure (I would cut 6 because I am adding three structures).
You will assemble rectangle like structures out of the four 2X4s (two ten inch pieces and two 23" studs). Once you have these screwed together you will screw them to studs from are previous frame. (SEE PICTURE BELOW)
