While writing keep the background of your story at the forefront of your imagination. You may not use all of the background information in your story, but keeping it at the forefront allows you to keep it pictured while writing. Children like to be able to visualize what is happening. How would they picture the story? Take a step into their shoes, what would they visualize? Picture books add many of the background details with their illustrations. Try not to over explain your background. Allow the reader to utilize their imagination. Isn't that part of the fun and wonder of books?
