False Flag Sorbet. Usually I wear stretchy knit cotton garden gloves that have little rubber nubbins to help me get a good grip on the quilt sandwich. Those have worked pretty well for me, but they are a pain because I frequently have to take them off to re-thread the machine or remove pins. They also get pretty hot when you're really zooming through the free-motion quilting.
So when I saw these Steady Betty Bands in my local quilt store they looked like they might be a good solution. Plus they weren't terribly expensive, I think they were $16. I'd also had a great previous experience using the Steady Betty Pressing Pad. The Bands are made with the same foam-grippy fabric surface that the pressing pad is made with.
I found that I didn't have to remove them to re-thread the machine or remove pins as I quilted which was great. And my hands didn't get hot because not much of your hand is covered when you're using them.
Two thumbs up from me, I'd definitely recommend these if you do much quilting.
