FAQ for Writers and Illustrators:
If you want to write and/or illustrate children's books ...
* Read: Both authors and illustrators will benefit by reading books like the ones they want to create. Look at how the pictures integrate or enhance the text (this is important for writers too). At conferences, I've heard the suggestion that you should read 100 books in your genre BEFORE you start writing. Don't forget to read other types of books as well. Just because you think you're a picture book writer when you start out doesn't mean that you won't find young adult novels a better fit for your story ideas and writing voice.
* Practice, practice, practice: Just like performers that want to get to Carnegie Hall, writers and illustrators need to practice and perfect their craft. Maybe I should have said, revise, revise, revise.
* Research: Everyone expects to do research if they're writing non-fiction, but you might need to do research if you're writing fiction too. Another important area of research is the publishing industry. It will help you target your submissions to the editor, agent or art director that's the best fit for your work. It will also teach you how the industry works, so you know what to expect regarding wait times on submissions, acquisition process, whether you need/want an agent, contracts, publication, promotion, and everything else that might pop up in your journey to be published.
