I glue baste and use a 12 inch round hoop. I've learned on this last quilt that leaving the quilt in the hoop overnight seems to tweak the fabric making it pucker in areas. Once I quilt over it though, it goes back into place with no visible puckering. Since then, I've stopped leaving it in the hoop and the stretching is gone. I've pinned the sandwich and thread basted and in my opinion, nothing holds better than Elmer's school glue.
