Supreme Sliders are great but also really expensive. I bought two sets of these and stuck them down to my sewing table with double-sided tape and they're GREAT! Nice and slippery and a fraction of the cost of a supreme slider, especially when you figure out how much these cover. My whole table is slippery now, it's wonderful.

I also agree, gloves! Or some sort of fabric gripping device. (dry sponges will even work in a pinch)
