I love this book for many different reasons. I have refered to this collection of larger lined, and frequently less detailed (than the circular mandala books I also love) offerings as a sort of "gateway drug" and introduction to the world of mandala coloring. Many times I have purchased mandala books as gifts. Many times the intricacy of these books becomes overwhelming to people with no experience coloring mandalas. This book is PERFECT as an introduction to the world and the joy of both coloring and mandala.
As said many times, each design has a page to itself. No design on the back side of the page not only let's you worry less about bleedthrough , it also (nearly) insures that you won't be throwing away the "b" half of the designs.
I will also say that, as a long time mandala lover, I find myself favoring this book. It might be that I can color them without sharpening my pencils every 8 minutes... It could, just as easily, be that these designs are beautiful, fun to color and don't require the hours of work that can go in to a detailed circular design of similar size. Mostly, I love that these are mandala with a twist.
I wouldn't hesitate picking this one up. There is enough detail for the "pros" to enjoy these as a relaxing excersize while being sure that, even if this is your very first mandala coloring book, you will succeed in creating beauty.
