Flour sack rig - Spine Tips #4

Welcome to a new Spine Tips video! This time we will learn how to rig a sack using techniques that you will find useful for any biped skeleton.
Animating a flour sack is a common task when learning 2D hand-drawn animation. It also serves as a great starting point for learning character animation. The sack is a simple rectangular shape so it's perfect to learn to pose and apply animation basics. If you can convey emotion with a simple sack, you will be able to do the same with a more complex character. This same hip-spine-shoulder setup can be used when building your other skeletons.
Follow along and create your own rig, then show off your animations!
