I really looked to see if it could be pulled out but it looks like an actual thread in the weave is black in a 2 inch line. I machine applied a flower motif over the spot and I hope it will not be too hard to machine quilt over when I FMQ the quilt. The appliqué of course is not where I want it but it is somewhat towards the bottom so I've made a label to go by the flower to look like I planned it that way. I am going to hand stitch the label on after it is quilted. Not the way I wanted it but at least I don't have to scrap the back.
