With my shortarm, I used to stitch the three layers together across the top before attaching the quilt to the take up leader. I let the quilt top and batting float over the other bar. Now that I have my Bailey, I now attach the backing at both ends of the frame (also done with the shortarm). I lay (float) the batting on top of the backing and then the quilt top. This time I pin these two layers down and then baste across the top before taking out the pins. Those pins are placed below the basting line so that the needle does not go over them. I may try using glue (probably a bead of Elmer's school glue?) to attach the batting and then the quilt top. I still float the batting and the top over the other bar. When I get near the end of the top, I pin the bottom edge down so it does not flap during FMQ. Thanks for sharing the glue idea!
