I don't like spray baste at all - it gets all over everything in the room and if you do it outside, you have to wait for a non-windy day. I pin on a double bed, draping the backing over the edges (if larger than top of bed). I smooth the backing over and over again until taut. Then I lay the batting over that and smooth it over and over til taut. Finally, I lay the quilt top over it all, smooth with my hands until I am satisfied. Starting in the middle, I slide my cutting mat underneath and pin every 4" or so. It works for me! When I was first quilting by machine, I used the batting that you fuse with an iron. It worked OK and got me used to machine quilting. Now I use Warm & Natural with pins. If the quilt is large, I do it in sections.
