I'm sorry, I just don't see it. If you felt she was criticizing you, I'm sorry you felt like you were in that position.
But, I now cringe when see the words Quilt Police thrown about...seriously? I don't think the situation was that at all, and I feel a bit bad for her now seeing what everyone is writing about her. This woman we don't know, who didn't say anything terrible, in my opinion.
There are no quilt police, there are people who's opinions differ then ours, that's all. and you know what? I haven't a clue who this Sharon Schamber person is, never heard of her.
You know, this post could have gone a totally different way. "Hey, I got to teach a quilt store employee something new today! She never heard of.......method or Sharon Schamber!" How cool would that be.
anyway, that's just my two cents. Again, I'm sorry if you felt you were put in a position where she was critical of your method.
