I actually skewwed the back on one of my recent quilts, still not sure how I did that, but I ended up with about four inches short on one corner, and did not notice until it was nearly all quilted. I just cut a piece off the excess on the opposite corner, appliqued it in place, and embroidered along the stich line, and used it for the label to make it look intentional. No one knows it was a boo-boo except me!
