This is what Andy Warhol is famous for. But most of us never learn about what he begin with which is his blotted line drawings. He was a graphic commercial artist who drew shoes for magazines and weather graphics for the news!
Sometimes, he came up with silly sayings for his shoes as well. 
We began by drawing our shoes using observational drawing skills.
Then we used wax paper to transfer the image to another sheet of paper with india ink.
And each artist chose to leave their image black and white, add watercolor, patterns or add a silly saying.
