I love spray basting! Especially for small to medium size quilts. I set up a big piece of cardboard on a card table outside with a sheet on it. Lay the back down first; spray the back; roll the batting and then unroll it onto the backing; spray the batting; roll the top and unroll it onto the batting. The rolling is important so that you get things smooth as you go. Need to do outside because of the odor and need for ventilation. Also I didn't want to chance sticky on my floors.
