I am working on my very first quilt, and am almost finished, or so I thought; until I realized that several of my stitches are coming undone because I forgot to back stitch. I should have known better. I need to get this quilt finished ASAP, as it is going to a family as a memorial quilt. I want it to look nice, so my question is---can i remove the unraveling quilted stitches and then restitch over the same line, but make sure to back stitch this time? Since I have already quilted the cover will this be a problem? (I am making this quilt using my machine.)

The example....My quilt block has an "X" in the middle of it. It is unraveling since I didn't back stitch. Can I remove the stitches from the "X" and go back over it? Will this make the quilt look odd or will it hurt the batting since entire blanket has already been quilted? I don't need any more mishaps, but I can't send it with loose stitches.

Thanks for any guidance you can provide. I am definitely learning from my mistakes.
