I recently took a three-session watercolor painting class at CREATE Arts Center with my boyfriend Marc and our friend Matt. The class was led by Sulay Khin, a very talented watercolorist and alumna of the Maryland Institute College of Art (MICA). The lessons were pretty advanced but we had a good time. I also liked that the class was affordable.
My only suggestion would be to spend less time on the initial drawings so we can get right down to painting. We sketched our flowers from real-life artificial ones, which is a lot more challenging than drawing or tracing from a photo. Just my thoughts!
