I did it once and was glad I did. I loved the quilt and did not want to waste all of the beautiful fabric and lots of money. I set aside a bit of spaced and worked on it an hour a day until done. I re-quilted it. After I washed it all evidence of the previous quilting was gone and it looked great. My problem was that I had used a quilting thread that was absolutely wrong. I used white, 40 weight thread on dark colors. Ugly! I re-quilted with a matching color and it was quite nice. Glad I did it.
