We finally started working on values with this egg drawing on Saturday. But the traditional process of rendering was quite different from what I was used to. We never used "blending" to make the 9 value scale on the right. But used layers of lines. The more layers you put on, the more values you get. We used vine charcoal with very fine tip. I spent about 90 min to make the scale. Then I could spend only about an hour for actual egg drawing. Finishing the egg is our homework assignment by the next class in two weeks (no class over Memorial Day weekend).
