I have one I purchased from second hand shop for £5 . It is a long rectangular one on a home made frame with lockable wheels. It gets used for all sorts. Displays quilts. Hand quilting. But not thought about using itforsandwiching. When I purchased my father said, what's that for ? Only thought hand quilting but I have even put towels on in a spare room for visitors. Keep it and keep inside your house and display your quilts.
