You have all come up with some very good ideas, thank you so much. The one I saw was like a 3 inch board running up and down, okay vertical on the wall and the slits were cut in it like in the board Nantie showed, but then they were loaded so they were vertical, didn't take up much space because I could put it on a wall that can't be used for anything else. It is a cement chimney that I painted over and sticks too far out for shelving, but I could put rulers up it. I wish I could remember things better. Thanks for everyones help and ideas.
