The 'experts' who wrote the advice reproduced on the dividers are aged between 9 and 13, and their notes are printed on eight asymmetric dividers throughout the notebook. Here's a bit about the Ministry of Stories:
The Ministry of Stories is a charity that aims to inspire young people through creative writing. Founded by Nick Hornby, Lucy Macnab and Ben Payne, and operating out of the Hoxton Street Monster Supplies shop, they run workshops and provide one to one mentoring to local children.
Creative director is Alexis Burgess and the designer on the project is Ed Cornish.
As a charitable organisation, the budget was limited which meant the project was a labour of love which included some of the printing being done in-house! Guillotine cutting and wiro-binding handled by Dash Finishers based in Croydon.
