My DD & I must be the only quilters in the world that don't like this product. We had high hopes - had read so much good about it, but even the both of us could not get the blasted quilt layered with no wrinkles. It would have been faster to hand baste it, as I've been doing for years. We are hand quilters & DD said she thought it made it harder to quilt, based on her experience quilting the matching pillow sham which hadn't been sprayed. I also have COPD & with all the prep for overspray, the masks needed, etc, it was more trouble than it's worth to us
