I think a supreme slider does make a positive difference! However, mine slipped and I sewed through it. It was a mess getting it off the back of my quilt. I really didn't want to pay a high price for another, so I ordered a Teflon oven liner from Amazon, following a suggestion from someone here. It was inexpensive, larger than the supreme slider and did the same job. Only difference is you have to use painter's tape to make it stay down on your table and cut a hole for the needle. But after sewing through my expensive slider, I would tape it down also...
