I love 505 spray. I have opened the window and there were times that I have not opened the window.
Usually my batting is larger than my quilt top and backing so I don't worry about the overspray - the batting catches it. Just spread everything on my floor. Often I have to move my table and chairs to make room
I don't spray baste much at all anymore. I can't get myself to spend the money on it. I use elmers glue
