In lesson 13 of figure drawing we'll finally be tackling the arms. In some ways, arms a little easier to draw initially, but things can start to get complicated once we start adding in rotation and muscle areas. So in this lesson we are going to break it all down and figure out the best approach to constructing them.  As always, there will be a series of lectures, followed by some demonstrations, and at the end of it all there will be a timed drawing exercise session for you to follow. This lesson also works well with the How to Draw Hands lesson.
