Oh no! That's always my fear after I finish one and run it through the washer and dryer. I close my eyes and hold my breath until I get it unfolded and take a quick look. Then a huge sigh of relief when all seems alright!! I do hope you're able to repair the seam because it's a beautiful quilt!! By the way....I used some of those same fabrics in my rag quilt. They're so pretty!! I'd be interested in hearing how your repair was made if you can post about it. Keeping my fingers and everything else possible crossed for you.
