I attended that workshop with Cat when she was here in the fall of 2007 to speak at a fund raiser for the Vermont Cancer Center. She is friends with the the woman who manufactures the Denise Needles. Her brother, an ocology specialist doc works in my department. If you purchase the pink set, $5 is donated towards breast cancer research.
Cat is extremely witty and I thoroughly enjoyed the workshop. I won the door prize that day to add to the excitement.
