One yard of JoAnn's heavier clear vinyl draped over the surface should help. Mine has a hole cut in it for the needle area and I use one piece of tape there. If you're sewing on a table, put the machine and extension to the right so you have as much vinyl covered table as possible to the left to support the quilt. My ironing board sits at an angle to my left to help if the quilt is heavier. Gravity is not your friend when FMQ. A yard of vinyl is 45" wide so it smoothes quite a few edges.
