I paint primarily with oils and soft "chalk" pastels. Folks often have a hard time guessing my medium, because my pastel paintings are usually quite smooth and blended rather than feathery and layered.
I love painting with oils for their rich, lustrous finish and ease of framing. I love pastels because I can pick up the beautiful pigments with my fingers without having to mix the colors. However, the finished paintings must be framed and stored under glass.
