I use a clear plastic bag that originally contained a set of new sheets. I punched a hold in the top flap and stick the left front leg of my clear extension table through that hole. This allows me to put the roll of binding for my quilt in the bag and feed it to the machine without it ending on the floor, unrolling and getting messed up. If I don't need it for binding I can use it to hold scraps that I might want to save from ending up on the floor.
