That is a terrific idea and I must try it. I layer the top of my table with cutting boards and the blue tape works good for smaller items that will fit on the top have to get my act together and see about those clips. Elastic is easy enough to find. I was wondering how many of these things you use on the large quilts so I can get enough supplies. I see you only use 2 for the width and 2 for the length is that enough?
