By using your method, I could achieve final closure on the backing by doing SID along the turned-under backing "seam" by machine, same as the rest of the quilting, although I'd still do enough handstitching along that closure to ensure it'd stay in place when I anchored it with SID.
Thanks! Everyone's input is always so helpful & appreciated.
