I have peg board that I hang my rulers on. Sometimes I want someplace to hang just the ruler I'm working with (table space is limited) I use a double ended hook, it is for hanging plants/hummingbird feeders? I got it at the Dollar store in the plant aisle. I hang one end of the hook over the back of my chair and hang the ruler from the other hook end. Look for over the door metal hanging racks at the Dollar store too.
