“"Some picture book artists are very consistent with their style, which is probably a good thing for business and career. My favorite artists are the ones who try a different look with every book. That’s why I like the Provensens. Everything they did had a lot of experimentation going on. Like children who haven’t yet been told not to splatter ink onto their drawings, or not to mix oil paints with watercolors, or that the sky is blue, not green … my own paintings from The Stinky Cheese Man I made the textures by combining oil paint with water-based varnishes. You’re not supposed to do that. It makes the paint bubble up like little pebbles."”
