Long Arm Dilemma
After I load my backing, batting, and quilt top onto my HandiQuilter Avante, (and I really strive to get everything even along the top edge)......I keep the backing taut (not tight) by using the side clips; but after I get about 1/2 way through the quilting, I start noticing that one side of the backing is sagging. I've pulled it back up taut and pinned it in place to the backing bar roll and proceed. So far the end result has been acceptable with no puckers, but after two such episodes, I know it's something in my procedure....at least hopefully something that can easily be corrected . Any suggestions out there? Thanks for your input.
