I do not have room for a design wall either. What I do is lay a flannel backed tablecloth on my bed and use that. So far I have not made a queen sized quilt using this method, but when I do, I will lay it on the floor. It folds up great and nothing comes off the flannel. I used to lay my queen size quilts on the floor, but never again. I guess regular flannel would work good too, but the plastic gives it good support.
