I've just recently tried spray basting. I stared on very small projects and found it worked really well. Those I machine quilted. Now I am working on a nice sized table runner and am hand quilting it. I spray basted it and the quilting is going very well. No sticky residue on the needle or thread. What I did have trouble with was getting the whole thing smoothed out. I don't have a basting wall, so I did it on the floor. Thankfully my daughter was around to help out. I didn't think until I was finished that I should have taped the backing to the floor. I think that would have helped a lot! We definitely learn from trial and error.
