I thought I'd do a little tutorial of my process of how I go about creating a plasticine illustration. Since it is a bas-relief, I start with the background and work forward. So to begin, I cover a piece of illustration board with a thin layer of plasticine. This gives the other layers of plasticine something to adhere to. I usually choose a colour close to my background, so in this instance it is a light blue for the sky, and brown for the dirt and ground. I basically press and rub the plasticine into the illustration board with my thumb and fingers. I leave a 1/2 inch gap or so, of illustration board around the artwork, so that it can be framed without loosing any of the edge detail. I also cover these edges with "Press-n-Seal" to keep the edges protected and clean until it is framed.
