I'd recommend this book for pleasure drawing for anyone school age and up. The way that she takes each of the large images, shrinks them down and tiles them , createing an M.C. Escher-like pattern. The paper in the book is very thick and takes marker well. You don't have to worry about color bleeding through the paper because the butterflies are only printed on the front sides of the pages. This makes it easier to cut the images out for decoupage as well.
Pictures come alive with the artist's choice of watercolors, markers, crayons, etc.
It is not just a coloring book. It is also a story. My 4 year old enjoys reading it as a book and coloring it. It has provided hours of entertainment. The gigantic pages make it easy for us to color together.
