I never spray baste, only because I don't like the fumes. I have a 60" sq table that I drape the quilt over and use safety pins to baste. I then move it around on the table and the draping sections put enough tension on the quilt to keep it nice and smooth. I have never had any problems with pleats or puckers doing this way. Not only that, but, I am not crawling around on the floor and it is alittle easier on the back.
