Preston Blair hands. Always a useful thing to practice and even more useful to master if you are an animator. I think it was John K., creator of Ren and Stimpy, who recommended drawing an entire page of Preston Blair hands. So, I did some last night.
The method is to draw a circle, add an area for fingers and a thumb so it looks like a mitten. Add a bit more flesh around a thumb. Then flesh the rest out. It is also extremely useful to draw cartoon hans by looking at real hands.
