I am thinking about making a frame out of pvc pipe, I can make it big enough for all of the pieces for a king sized bed. It will be light weight and easy to hang. I will attach a flannel to it. I am also going to make a smaller one to hang next to my sewing machine that will be big enough to hang several blocks on at a time, and that will be easily removed from the wall so that I can go back and forth with the blocks from the design wall to my machine.
