I got this colouring book last summer and the designs were basic enough that I was able to do up to four pages in a very short amount of time. The colouring books are starting to pile up in the back room and I need to make a serious dent in them.
It's a cute book. Good for kids or adults. The design is on one side with blank behind it so it was perfect for markers. I always slip a piece of paper under the page to protect the next one just to be on the safe side.
My grey markers pretty much ran out after this book; I was using Crayola. Good thing I got more!
Of course my choice of colours for each beast was purely conjecture on my part.
I would recommend this book for it's whimsy and ease of colouring. While I do enjoy the very detailed books, every now and then it's nice to have large swaths in which to fill in.
