I bought the very same oven liner today at bed bath and beyond had a 20 percent coupon and am so happy I bought it. It works great. I kept mine in one piece. Placed it just to the left of the needle. I also have the supreme slider which works great but is small and I accidentally was pulling it away from my machine when it tore because I did not see the bobbin thread was pulling away from the needle hole. I taped the cut but it is very fragile now. The oven liner is much stronger and pliable and the price is right. Thanks to the people who give these fantastic tips on The Quilting Board.
