I love, love , love my supreme slider. There are 2 different sizes. I have the smaller one but would love to have the large one. I don't FMQ without it. I find my quilt slides better and my FMQ looks so much better. I also find my shoulders don't get as tired. I would be interested in comments on the silicone spray. Sound interesting. I also love the machingers gloves. I feel they were both worth every penny I paid for them.
