I ordered one from Nancy's Notions on sale from $24. down to $19. and I am very happy with it! It has grommets along the top side and is a flannel on top - underside has squares to be precise when putting your squares/rows on it, they show thru. The size is 60"x 72".
I rent and hesitate to put hangars on the walls so I bought a pkg of 3M Adhesive hooks that leave no marks when you want to take them down- advertized recently on TV -pack of 6 sells for under $5. I think. I did every other gommet and am just in love with it. Was away and left the entire sheet filled with unsewn quilt and all were still sticking when I returned 10 days later. The thing does not stick to wall but just hangs against it so no harm done to wall. Hope this helps. Victoria
