There is a younf lady that I know that teaches classes in Point Richmond. Really nice area, so dont confuse it with Richmond, Very different. Her name is Lori and the place is called The Nova Studio. her web site is www.thenovastudio.com She isnt teaching the hydrosols but she teaches quite a few of the classes. If you want to learn basics as a starting point she is great. That is where I learned a few things and then went back and expanded on what I learned. I probably have taken 6 or 7 classes from her and am looking to take a few more on the bath and body section. If you go tell her I sent you.
