I have this Jelly Roll quilt all done with the quilting (stitch in the ditch serpentine) and all went like a dream - until - I got out to the very edges in the border with the quilting and I wound up with the backing messing up and folding over, etc., now I have to rip some out and start over. This isn't the first time this has happened and am wondering if anyone else has had that problem and if they found a tip to prevent it.
