You wouldn't believe how remarkably patient the teacher was with a class of giggly adults. But that's what happens when you're in such a relaxing environment with great music, lots of messy paint, a blank canvas, and an awesome teacher.
And alcohol of course.
And if you've never painted since that art class in middle school (like me), you'd be surprised at how good of a job you can do under their very skilled supervision. I took my painting home and I sat there looking at it a while and I did feel like I was there on that hill looking across the bay at the city. (We did Van Gogh's Starry Night Over the Rhone that night) It really gave me an appreciation for what the real masterpiece might look like and I would now like to go see the original some day.
Oh and trust me, take lots of friends with you and trash talk each other's painting. It's more fun that way.
