I have used the spray stuff several times hand quilting and plan on using it again! It holds well, is repositionable in case you missed a wrinkle. I didn't have trouble with my needle getting gunky or with it being harder to go through the layers. The first time I used it was the first time I made a quilt with out wrinkles on the back and believe me, I tried hard to avoid them, always to no avail before this magic stuff in a can. I would give it 5 stars, but I don't have that option, so :thumbup: :thumbup: :thumbup: :thumbup: :thumbup:
