Sketchbooks allow for freedom - for the maker to daydream, vent, and explore in private. Some keep it simple. Some fill every page with scribbles, scraps of paper or tape. Either way, they allow us to get a glimpse of what makes that person tick; which is why Richard Brereton created the book Sketchbooks: The Hidden Art of Designers, Illustrators and Creatives. In it, the individual artists explain how they use their sketchbooks to create their finished works. These types of books never get old and are always insightful.
