DH cut a sheet of foam insulation board into different sizes for me. (not because he thought of it but because I marked the board and asked him to do it.) I covered them with felt and have a stack of them in my sewing room. I always finding uses for them. They come in handy when doing demos at guild, hold block pieces, pinning wet blocks to block into shape, I use the biggest one as a bulletin board to pin up all the misc things a quilting room seems to collect that I was constantly pinning to my design wall.
