I have heard about it, but hear it's a pain to pick the small pieces out. I use Sulky Solvy instead. You mark your pattern, attach to the quilt. When you're done quilting, remove the large pieces of excess and wash the quilt. The rest dissolves. It's great! I either use a Joann's coupon or buy when 1/2 price. I did a whole quilt with the small roll - probably about $5-6.
