Francis does a stitch that doesn't show at all on her applique. She goes beneath the top layer of fabric and just slightly catches the bottom fabric and then come out at the fold of the top layer of fabric. It hides the entire stitch. Good luck. Usually when that happens to me I find that the entire quilt is actually falling apart and I'm left to either use the entire quilt as batting for a new quilt or if it is a family heirloom to genty sew a transparent netting over the entire thing to hold it together for awhile longer.
