van Gogh painted copies himself. His favorite artist to emulate was Jean-Francios Millet. He did something like 30 copies of paintings by artists he admired. Here is a Wikipedia article about van Gogh's copies: http://en.wikipedia.org/wiki/Copies_by_Vincent_van_Gogh
In the afternoon we took a walk to McDonald's. A perfect walk, because it is about 3 miles round trip. There was a man who set up his office in a corner booth. He made a lot of phone calls and sat pretty still....so I used him as my model to sketch.
