I took a vinyl tablecloth (flannel backing) and sewed a channel into the short side. Slid a closet pole into it and tossed the pole over a set of bookcases. The weight of the pole holds it nicely and two tablecloths makes a very large design wall. One holds a twin and most of a queen sized it you do not need it all on the wall at a time.
I roll it up and pin it when I want to go thru the books.
