I spray baste all my quilts and usually use June Tailor spray from Joann's. Be sure to check, some sprays only last for a few days. I have tried spraying on a design wall (in my garage) and put newspapers on the floor, but the fallout from spraying makes the papers sticky and they stick to your feet!
I find it easier to do this on a large table. Also, I never spray the fabric....always the batting.
