There is no such thing as the quilt police. Just rude people with exasperating opinions! In fact, I do not even like that term, "quilt police". It implies that they are in charge. They do not get PAID, so therefore they are not the police.
I think that what you did on your quilt, ie, crossing lines when quilting the fish was probably a very cute design. Why worry about what a few silly opinionated women say. Just tell them you did it on purpose. They do not pay your bills so their opinions should not count.
