In order for you to be able to understand how to pose your stick figure to help you with drawing poses, you have to understand how your different joints work.I have three types that I'll need you to know. There is 1, the ball and socket join. This is the type of join that is in your shoulder and your hips. It allows your limbs to move more freely from the base. 2 is the hinge joint, like in your knees and elbows. They only move open and close like the hinge on a door. Then we have 3, the saddle joint. This is the type of joint you have in your wrist, ankle, toes and fingers. with saddle joints, the bones are sitting on top of each other and can move a little more freely than hinge joints but not nearly as freely as ball and socket joints.
