Yup the bed works great! I don't even pin anything down to hold it in place. It all seems to stay put. I spray left to right(the batting) the width of the quilt and then about a foot down. I then smooth the top or backing down on top of it. And move my way down the quilt. I like to spray the batting instead of the fabric. Seems to stick better. And doing smaller portions it wont dry too fast on ya. And the walmart spray works great. I have used like 3-4 different kinds and I can't tell that one is any better than the other. Also be sure and shake it the full 2 minutes or whatever it says to do on the back of the cans.
If you spray too heavy that might be why it wasn't sticking
