building shelves in closet
I'm building wood shelves in the back of my closet. My closet is 38.5 inches wide and was planning on supporting it by screwing 1x4 boards in an U shape along the edges. I want it to be sturdy enough to support books.
The shelves will be 14 x 38.5 3/4 inch plywood.
Is 1x4 overkill? Will 1x2 do the same job?
