This is a page from the Creature Camouflage Colouring Book - Hidden Exoskeletons. Its a great book because you can either camouflage the creatures or create colourful markings and have them stand out.
I love colouring in books and I've got loads of them - I don't care if they are for children! I like to do them just watching the TV or listening to music.
I did this one with watercolour, colouring crayons and pen.
