Thanks for the info. I didn't use 505 but I think it's Elmer's. It didn't seem to hold the layers too well and we wound up having to pin it too. I was afraid to use too much spray. I'll keep the alcohol handy when quilting it. I made the mistake of trying to sew stick on velcro to flannel and that gummed up the needle so bad I had to throw it away. I couldn't get the adhesive off even with alcohol. This isn't nealy as strong. Next time I'll use 505.
