Their biggest mistake was not creating a sequel sooner! Activities include: making up a new language, writing poems about ducks, and becoming an ogre! Also, make sure to check out the Hall of Famous Mistakes!

From the publisher: “After taking part in this five-week project, our Marvellous Mistakers expressed that they felt great knowing that it's okay to make mistakes! We want to share this revelation with the world in this publication working to push back perfectionism! Get lost in this activity book designed by Lily, Imogen, Freya, Mia, Alfie, Charlotte, Annabelle, Isabella, Elsie, Maxwell and Bella, to let go of the fear of getting things wrong and to play with making mistakes. We would like to thank our amazing volunteer illustrator Sylvie Gosselin for putting this book together and a huge thank you to all of our funders who without, this project would not have been possible.”
