I've never used one because most of the comments I've seen about them were negative. I started out pinning, then moved to thread basting because I hated having to stop my quilting to remove a pin. I haven't seen anyone on this thread mention glue basting. It's what I use now exclusively. I LOVE it. No puckers, no gumming up my needle, quick and easy, cheap and washes out nicely. Just remember it has to be Elmer's Washable School Glue. I'll never go back to any other method.
