I'm working on my picture book dummy right now, and it's so much fun! I plan on painting this sketch soon, so check back for the color version. If you write a picture book manuscript, you submit just the manuscript without illustrations to publishers to see if they will acquire it. But since I want to do both the writing and illustrating, I draw sketches for my whole picture book manuscript that I've written and submit those sketches along with the text as a small mock-up of my picture book called a dummy or sketch dummy.
