Our canned storage. I used a bunch of 2x4 scraps and two new 2x4's, assembled with 3.5" self tapping screws. Shelves are 34" wide, which fits 10 cans of Progresso soup with a slight gap. I made it 7' tall so it would make good use of the upper dead space on the wall. I also used a single sheet metal L bracket to mount the shelves to a wall stud.
