If you feel beguiled by complex colouring pages and are looking for something a little more entertaining and lighthearted, Theo's books are definitely one's I'd recommend. Here are the 3 pages I've completed so far! I can't wait to do more, and get the rest of Theo's books :)
Her series of books include "Dinosaurs With Jobs: a coloring book celebrating our old-school coworkers"," Fat Ladies In Spaaaaace: a body-positive coloring book", and "Mer World Problems: a coloring book documenting hardships under the sea" which I will be reviewing next time!
In this book as the title says, unicorns are jerks! Take a look at their escapades, there are 18 of them in the book :)
