I took several Bob Ross painting classes in 2010 and 2011 while I lived in Georgia. I haven’t found any classes around here lately, but I would love to take another. The classes are expensive but all supplies are included and oil paints are way more expensive than acrylics.
These paintings are 18 x 24 and oil on canvas. They were underpainted in black, grey and white by the instructor (it was a one day course). What was surprising is that everybody in the class painted the exact same thing but all the paintings ended up so different!
