I dont know if it is the spray or me,but I bought a can at JoAnns and followed the directions [shake the can for a full 2 minutes] then sprayed the quit backing from 10 inches, then layed the batting down on the backing and sprayed and lay the quilted piece on top of that. It was a little wrinkled so I tried to move it, and it was hard to take apart, really glued hard. Then I tried to quilt, and the needle got all gunked up and it would skip about four stitches where it would not sew then sew a bit more and skip. I had to rip all the quilting apart....yuck! I put in new needle and it did the same thing. Then I tried just putting a piece of the batting inside some junk fabric and quilted without any spray , and it seemed to sew fine. the can cost $12 so I am very unhappy. I hate to go back to basting by hand. Uny Ideas?
