Every page is unique, hand-drawn (iPad Pro with 2nd Gen Pencil in ProCreate) and the result of many quiet hours (the largest took over 6 hours).
The spine is glued so that pages can be easily pulled out to colour in separately, or to display on the family fridge!
The lines are a somewhat thinner than conventional colouring books, so these doodles tend to make you focus a lot deeper than usual. I sampled this myself after colouring in a draft copy of the book (images posted on Facebook and Instagram).
Some of the most seasoned colourists I gave a sample to found it a really enjoyable time keeping in between the lines and coming up with inventive colour patterns.
