I buy the 505 from
www.sewforless.com. They are nice big cans, at about the same price as the smaller cans. There is a slight odor that I notice only because I'm asthmatic. Bought 2 - 4'x8' - 1/2" laminate sheets at Menards. Put them on the never-used ping pong table in the basement for my table. This setup is perfect for spraying and leaving the room. Cleans off easily with warm water, and accommodates large quilts. Love it!
