One of my favorite author/illustrators out there in the land of children's books is the multi talented Mo Willems. You might recognize his name from a number of award winning series of books which include "Don't let the Pigeon Drive the Bus" and the Knuffle Bunny Series. Recently he did a wonderful interview for NPR dealing with "Getting Adults to Draw" and the reasoning behind why they don't anymore. It is really a wonderful listen and would suggest you check it out here. Also a fun link is to his website. Hope you enjoy and get back to doodling!
