This sub lesson is by Cassie Stephens. It is intended for the sub who is not an artist. There are step-by-step drawings of a panda for the students to follow and detailed instructions. It's super cute so give it a look. Here's Cassie's blog at "Cassie Stephens: In the Art Room."
If you want to follow that up with an early finishers' worksheet, here is a perfect choice.
