A Nasty letter that I want to send.....

Send it, but a modified version - take out any 'personal attacks' - times when you say *she* is a certain way - such as cowardly etc. and don't mention 'burning bridges' - you don't want to give her any ideas.

I don't think there's anything wrong with saying you felt disrespected, poorly treated and that you felt that they were making you look bad by painting poor replicas of your designs and that it was hazardous to the kids' well-being having non-facepaints being used. Let her know how much you've enjoyed working for/with them in the past and say that you hope that this situation will not reoccur in the future.

Best of luck!

(And what a PAIN that happened!!! :S)
