A thumbnail Page is a tool to use for the layout of a story. Each thumbnail square represents one page in the layout of the story. From the Title page to the end page--showing the order of pages and construction of a book. It's an amazing way to see a story with ideas for illustrations on one piece of paper. Perfect to use prior to creating a dummy book of a story. A dummy is a mock up of the story with illustration ideas to see the story in book format prior to making your story a finished book--a rough draft dummy of your story.
