Some time before I truly got engrossed in painting, I tried color pencil. The biggest difficulty I find with this medium is that there is no white. The paper is your only white and if you make a mistake and cover it, there is no going back. This is also the reason why I don't dare pick up water color! At least with colored pencil, I'm working with something as precise as a needle.
