Hands used to be the hardest thing for me to draw. I'd avoid the difficulty by putting hands in pockets or behind backs. Finally I faced it down by integrating the poorly drawn hand into my style. I would draw the hands as if I didn't care. People knew they were hands because of where they were, at the end of the forearms, so why worry? And I stopped worrying. Suddenly I could draw hands without any problem. It's like carrying a trayful of glasses. Going slowly isn't the answer; it's about not worrying.
