You know what I'm thinking? It looks shoddy. It looks like someone couldn't be bothered to do a proper job. The strip on one side offsets the center and it's just awful what she did to your quilt.
There's NO excuse for that one strip. You did the right thing in telling those ladies off. I wouldn't sew a single thing for them after that. That is so inexcusable, it isn't even fit to give to charity the way she altered it.
