A few days ago, someone posted asking what the "Quilt Police" look like...You found out first hand, didn't you?!
Now, if you can post a picture of her, or even a drawing - from your memory- then we will all know who to steer clear of!
You handled it like a pro. I'm proud of you, because I would not have been nearly as gracious and polite as you were!
I'm afraid that my solution might have involved a body bag and a coroners inquest!!! (maybe a quilted body bag, done all the WRONG ways!!!)
