My DH made me a portable design wall that I can move anywhere in the basement - it's on wheels. It uses the foamular insulation boards from Lowe's. It has panels on the front and back of the base that slide off and can be leaned against a wall side by side when I'm working on a larger project. I have Fons & Porter's design wall taped to to front of both sections and plan to put a darker flannel on the backs so they will be reversible. It works great for me.
