I'm in the process of adding 3/4 inch birch plywood shelves to a pantry. To maximize space, I'd like for the shelves to be 68 inches x 11 inches. Will I need to worry about the shelves sagging if they are supported by cleats along each end and the back? Also, I was planning on gluing and nailing wood edging on the exposed edge of the plywood.
Thanks,
Bob
