Salley from the Grace Company shared this tip with me. And it seems to be working. They sell a product called True Grips. First, you stick the little rings on the back of your rulers so they don't slip. Then you take the little dots (these come from the center of the rings) and use them on your templates so they won't slip and lastly you take the outer piece (this looks like swiss cheese now) and you put it on the bottom of your foot control. No waste and works great. Oh, I have carpet in my sewing room.
