I have tried the Supreme Slider and the Teflon oven sheets. The supreme slider is very expensive and you can sew over it in error as stated....the Teflon sheets work the same way and are so much cheaper. Be sure to cut a hole under your needle and tape (Blue masking tape or Frog tape) whatever you use down to your table. It's a pain when the bobbin needed changing, but that is a trade off you have to make.
