My husband cut some insulation boards (as mentioned above). His idea was to put them in the windows (north side) to cut down on cold drafts. This was awesome but in the end it did not work as the wood started to warp from moisture trapped between the two. However, I asked him to leave one set up in my sewing room. I bought some white flannel, sewed to lengths together and hung it from a curtain rod above the window (it hangs loose). This has worked very well for me and, yes, I can stick pins right into it if I need to. It can all come down in a few minutes but I have had it up for almost a year now. It is probably large enough for a lap quilt. Good enough for me. Whatever you decide to do, a design wall is so helpful. I love using mine. Yolanda Wood River
