I was at a resent mentor-ship workshop with George Glen in P.A. We were discussing my drawings and why I go over the first line that is accurate three and four times? I have given this a lot of thought. Habit? or confidence? Could the first line be true, from my heart, what I see. Then the second line be ego, (The left side of my brain saying that's not right) and the third line, fear. What will people think if the first one isn't right. So the next day I did all one line drawings. Loved it! Loved them.
