I'm gonna go out on a limb here and say it looks like a hand made, manufactured quilt. They come into this country by the tons from around the world. The large and loose stitching indicate speed rather than craftsmanship, IMHO. It just has the look that these imported quilts have.
I may be totally wrong too!
If it isn't to difficult to repair, I would do it to make MIL happy. Where did she get the quilt?
