If you have one, a wooden drying rack will work for a hanging display. I'm thinking of the ones that scissor in and out and lock in place. A folding screen can also be used if you find one that you can tack nails or hooks into. Any two pieces of wood will work with hinges so that it folds flat to travel and when open it forms a triangle shape. I've seen two long louvered/shutter panels hinged toether. Several louvers were remove across from each other to run boards through to make shelves and to keep the panels in the V shape to stand up.
