For these classes, you are allowed to BringYourOwnBeverage (see beer or wine, etc ;) ), you pay the $30-$40 (depending on size) for the art piece you want, and you are provided all the supplies from the canvas to the brushes to the paints. Once the class is over, you get to go home with your very own piece of art that YOU painted. It doesn't matter your skill level when you go, it will turn out however you want it to. The awesome thing is to see the variety that comes out of the same class, with the same instructor and all the different choices people make and ways they paint.
