I use those from Fons and Porter and the Machingers. I read on a forum once that a lady used Glycerin. I found it at Wal-mart for about $2.00. Just a couple of drops in the palm of your hands. I rub it in real well and then wipe the excess of on a towel. I've had pretty good luck with it, it helps grip the fabric when you are quilting. You can still thread your needle and pick things up. So far, I've not had any spots or stains on my fabric.
