Basically, you sign up online, pay a fee, show up at the venue, and an artist leads you through the creation of a beautiful painting! I have gone twice in the last month, had a lot of laughs with my good friends, and came home with two beautiful paintings. At one of the events, about 60 women (mostly) were painting together, and everyone was having a great time! They play great music and you can order food and beverages (including non-alcoholic drinks) while you paint.
Here are some photos of my friends and my adventures with painting:
