As I mentioned, a painting this large (24" X 60") takes some extra planning in its execution. For Stage 2, I do a rough drawing of my subject(s) using a 4H pencil. Here I have the gessoed board on a drawing shelf. I then prop up the backside with an array of big fat art books. The thick drawing board gives the 1/4" gessoed painting board adequate support and helps prevent warping.
