Well, I used it once on the quilt I'm doing. It didn't work.
I followed the directions and ironed it to the fabric. Was nice for about 14 minutes.
Now I've quilted the quilt and it bunched, and came apart. I won't buy it again.
BTW when it came apart I spray basted it together, and the spray baste wouldn't stick. My first time for that to happen. Used 505.
