I think I was the one who brought this up...I saw it demoed at a guild meeting and there was a run of it at our Home Depot afterwards.......me included. But I must confess I gave not used it yet. The demo claimed it was good for embroidery stabilizer and also machine appliqué...where you sew, slit, and flip out and machine sew to background. The price is much lower than fabric stabilizers, but good to know about lowering heat on iron when using.....will remember that. Personally, I had never heard of this product....I found it in the plumbing supplies aisle....
