I like your idea of a two sided design wall. Very cleaver idea. I go to two retreats a year and needed a simple travel design wall. . I made a flannel cover to go over the folding cardboard pattern board. It folds up, is sturdy enough, and very lightweight.

Onebyone....what a brillant idea using the folding cardboard pattern board! Would you believe I have one setting in the corner that I've never used?? I could sew a pocket down the length of the sides and insert a wooden lattice to make it stand up by itself or lean against a dresser.. Thank you so very much this idea.
