You know, MarleneC, you may be right. I think my newest machine may have one of those gadgets. Unfortunately, most of my sewing stuff is already packed up as I am preparing to move to Va soon. Darn! And I hadn't even thought of using styrofoam. But I am beginning to think there is a problem with the screw as there seems to be an awful lot of play in it. Oh well, Amazon says my order should arrive in a day or so. Thanks everybody.
