If the fabric moves at all while quilting, you will end up with puckers/pleats. There are many different methods for basting the sandwich together and I think I've tried them all. I've recently tried using liquid washable glue (Elmer's School Glue) with wonderful results (better with cotton batting). I like it much better than spray adhesives because I know that the glue will wash out 100% with no staining. I can machine quilt through the glue, even the spots where it globbed coming out of the bottle. Once the glue is dry (ironed or airdry) the sandwich is secure and won't budge, regardless of how much handling it gets during the quilting process. The best part of glue basting....it is very cheap!
