I finally figured out I could make a large hem in a flannel backed tablecloth and put a wooden closet pole in it. Then I "tossed" it over a bookcase and the weight of the pole on the back keeps it hanging straight. Now what I need is a bigger tablecloth that would hold a 100X100 quilt.
However, I will wait until I find one on sale. Whole thing cost around $20 or less.
