I had a seam separate on the back of a quilt. it was after it was long arm quilted, so it was hard to pull back in place. anyway, my quilting friend tried a patch, but it did not look right. Being a needlepointer as well, i whipped out my needle and DMC floss and did a satin stitch to join the fabric. looked great, since I was able to use a floss color almost identical to the fabric.
