There is one on the market that opens like an old projection screen. That one I'd like to see. I just tacked up backing on my wall and it hold the squares I'm working on Don't bother with the "don't need pins" fabrics. I did and it did not work. I also know many that use the back side of "oil cloth" the kind you buy at Ace and little ones use to draw on. It is a nice heavy fabric and the back (the side you would use) is a flannel like material
