Fons and Porter's website had a portable design wall. It cost me under $25.00,it is gridded so that I can keep the quilt nice and even. I bought some of the Command portable hooks that you can put on the wall and take off with no residue.I really like it. I don't have space to put a permanent design wall and unless I win the lottery tonight, I won't have anytime in the future. I kept the bag it came in and when I'm done with it, I store it back in the bag.
