This terrible issue is just another reason for me to continue to wash all of my finished quilts before they leave my house. I wash for a couple of reasons, but primary to check for color fastness, to make sure none of my seams come loose, check for loose threads, make sure I quilted enough so that the batting doesn't shift and lastly because I love the look of a wrinkled quilt (personal opinion). I also sew into my binding seams a care label, think that helps the new owners with washing....
I wonder if the fabric was OLDER which made it less colorfast.
I wonder how it was washed ???? Hot water ???? and/or strong detergent ?????
