I use the Dr. Scholl's moleskin padding that you can cut to whatever size you like. It sticks onto the machine beautifully and doesn't move until you pull it off. I use it when I teach quilting to kids ages 10 to 14 whom I find have a much harder time keeping their seams consistent. Then I just pull it off when they go to do zig zag stitches to hold down their appliques. It's cheap (about $2.99 a package)and works beautifully as it creates a nice ridge for them to butt their fabric up against!!
