I couldn't do without my design wall. Well, truthfully, I suppose I could do without lots of my toys, but they do make life easier and quilting so much fun, don't they. Someone in my guild told me about her mobile design board.....she used a trifold (science project) board covered with a light flannel sheet and pinned/glued tightly when the board is opened. She loves it. Maybe you could give that a try for something that is easily moved.
