Collard Green Leaf This is a picture of a collard green leaf. This is one of my favorite pieces because the drawing process was very simple and fun. We had to outline the outer part of the collard green leaf and shade in the inside. I used my charcoal pencils, charcoal compressed pencils, and magic rub eraser to erase any unwanted markings. This is a beautiful drawing! The collard green leaf feels very soft.
