The one picture book I've written hasn't sold to a publisher. The books I published were all classified as middle grade or early reader. So I don't have any info to share about successfully writing a picture book. And I am not an illustrator, so I don't do that part of picture book work.
However, I would advise you to:
- Spend some time in your local library reading picture books and picking out ones you like.
- Then look those books' authors up on the Internet. Sometimes authors will have information at their websites on writing. An example is Josh Funk, who is a New England writer who has written and published picture books. Be sure to read his section "Picture Books Are Short." Many new picture book writers don't understand that
- Take advantage of any opportunities to hear picture book authors speak in public. They make appearances at bookstores and sometimes libraries. They often will speak about how they wrote a particular book or the publishing process, and they may take questions from the audience.
I should have also told her to hold onto anything she writes, anything at all, in case she can use it again. For, example, a blog post.
