I am a learner too, I am currently working on my third ever quilt, they have all been crib sized. I used straight pins on the first one (ow ow ow!). Then I bought some bent safety pins for the second one and got so frustrated with how fiddly they were to put in, I went out and bought some 505 spray. LOVE IT! Once sprayed and sandwhiched (Use Elizabeths instructions above - they are great) the layers didn't shift. I was concerned the quilt felt a little stiff (like light starch) but that went away after one wash. A can has done two generous crib sized quilts, three quilted cushion covers and is not quite empty yet.

Karla, it feels like light hairspray, except when it dries it is still very tacky. I think if you don't wash the quilt afterwards it would be fine, it would eventually disappear with movement, kind of like hairspray too.

I always used pins then listening to all of you I tried the spray. I'm a believer. That was so nice to not be messing with pins and it was faster and no puckers on the back and I could go on and on. I love it. No more pins for me.
