Yesterday I held a small workshop on the Word festival in Vancouver, meeting with aspiring children's book authors. It was fun, hope to do it again next year. I couldn't take a good picture in the middle of everything, so no photo :)
Everyone had different projects, but I think two statements which applied to everyone were:
1. Identify the specific age range you're trying to reach (3–5 etc.)
2. Have a clear synopsis of your story
Most people are not sure where to begin a conversation about their project: the best way is to describe your audience, their needs, the main characters in the story and the story itself. Also, it's very helpful bring samples of your work with you. Good luck, everyone!
