As in Eva Hesse's paintings, it is possible to get a 4 year old and a 1 year old to emulate an artists style, sort of. I began by showing the kids this painting by Wang Hui. First asking them what it looked like then asking them to find things like the people, the buildings, and the trees. I explained what the artist was trying to accomplish and then demonstrated how to draw a line and then make a similar line underneath, over and over.
