I went to the site to check out their design walls. Very nice idea. Don't see why it can't be made ourselves if handy with tools.
I made a design wall using some batting stapled to my basement wall (chipboard, not cement) then added trim pieces like a frame to spiff it up a bit. I take my vacuum to it occasionally to get all the lose threads and spray a quilter's sticky spray occasionally when the blocks won't stay up on it. I can even use my iron on the quilt top to get rid of the wrinkles before I take it to the quilt machine. So far its worked for me.
