Try using a Silicone Spray. I spray my whole table, and it's nice and slippery. I spray my presser feet too. It won't hurt fabric, and is washable. It dries right away too. I use it in my kitchen on my counter tops too. It makes them shine. I get the "Misty Silicone Spray". you can get it at any fabric store. I ordered a whole case of it on line. I use it for everything. Try it and if it doesn't work, them try the silicone sheet.
