I love it!, I have a tendency to make "too Big" quilts, and this is perfect... spay it on the backing, apply the batting... if it has a wrinkle just pull it up in that area and re-apply... when you have it like you want... spray the batting and apply the quilt top, I do it in rows so that it's not so apt to wrinkle and bunch.... NO MORE PINS!

and I used it for another problem too... I had a handicapped person who was to stay at my home, but with my flooring it was so slippery with the rug... so I sprayed the RUG bottom... it worked, and it wasn't so hard to clean up after they left... LOVE it!
