some times even with the spray you still need to either baste of pin around the edges. all the moving around pulls the sprayed layers around too, pinbasting the edges helps keep you together. I think the spray is best used on small projects, like wall hangings and table runners, it seems there are always problems when using it on larger projects. it helps to start in the middle and work your way out smoothing as you go. i hope it turns out ok when you are finished. it does take practice. I have never had any luck with the spray on anything larger than a table runner and i still had to baste all the way around it.
