Ok i have only just started filling this book, the first page is scary as it takes a little while to get used to being allowed to create mess! On the second page i poured coffee on the book from a height which was surprisingly fun, once you get relax and get creative this becomes a good outlet for stress and just to feel a bit silly, i do feel like i am doing something naughty and silly when making so much mess, but its definitely a good thing! Good for anyone who likes breaking the rules! Only minor flaw is that i would prefer bigger pages for making mess as the book is quite small! But there are a lot of pages and so many different ways of making mess so its not too bad!
