I've spray basted small & large quilts I had good luck with it. I've also used the fusible batting...had mixed results with that. I have always pin basted...but find sometimes if I'm not real careful that I get bubbles on the back. I hand baste smaller quilts. It seems like a lot of work to hand baste a large quilt but she gets lots of ribbons. So it must be worth the time. I watched her video with the boards. I think I'd like to try it first on a lap quilt and see how long it takes. I'm always in a hurry to get to the quilting!!
