I used that spray basting one time. In fact it was on one of my first quilts. I had no floor area that I could lay it out on but I did have a wall in my bedroom that I could use. So I carefully pinned my quilt to my wall. Opened up my window, shook the spray...sprayed it all over the batting got it sandwiched, took it down left my window open, sewed it, Went to bed that night, woke up SMELLING that nasty spray so I recommend NOT USING IT IN YOUR BEDROOM. It took several days for the smell to get out of my bedroom. But, I WILL use it again, just not in my bedroom.
