I started out with graph paper so I could make the best use of the limited 8 inch plywood strips that I had left over from my desktop. Then I cut the boards and painted them. Now they are on the wall and I love them. The angles of the horizontal pieces makes it so I don't have to use bookends. I do have to finish painting the wall and have decided to also paint the little door at the bottom corner of the wall. This is a cubby-window that is only about 5 foot wide and not really usable space.
