First of all, you should be proud of that quilt & there is no way this ‘serves you right’. Why is it wrong to be proud of our beautiful creations?!? It also isn’t ruined. As one who has trouble keeping points, I agree with your frustration at losing the edge points to someone else’s mistake. Others have given you good advice as to the best way to handle this with the LA, which I’m not qualified to do. I’ve never had a quilt LA’d.
