Big Book of Geometric Designs and Illusions to Color

WOW! I found out later that this book is actually four adult coloring books in one, with so many variety of images to choose from, I don't know which one to start with! Unfortunately the images are back to back, so I strongly recommend using the softer variety of colored pencils and do not use markers UNLESS you copy a special image that you want to use color markers for a special look. (If they weren't back-to-back, this book would be ranked a 5). Yet, one of the most important factors in choosing adult coloring books is paper quality as it affects the images...and the paper in this book is not cheap newsprint! So give this book a 4.5 rating and buy it if you are in to coloring a wide variety of geometrics and optical/visual illusion images.

I am an adult that loves to color and this book is great. There are 4 books in one, and some designs are more intricate (i.e., require finer tip media) than others, but it's lots of fun. Very good, cheap, relaxing therapy! Can't miss--these would be fine for older children as well that are very attentive to detail.

I'd give it five stars but some of the designs are just too complex. You can sit there for hours trying to find 'the pattern' to color. The majority of images are outstanding and a blast to color. The few you may skip or come back to later when everything else is done don't really detract from the value (both fun and monetary) of this gigantic coloring book. There's SO much to color you won't run out anytime soon. Well worth the money.

I have quite a few coloring books and this one is definitely in the top two. I especially like the variety in the book. The concentration to focus on coloring the shapes is very stress-relieving for me.

This is 4 books in one. Designs range from simple to extremely complex. I find the complex ones to be a challenge, but I really enjoy them. If you like coming up with color schemes applicable to designs, then this is a great book. It is a form of relaxation for me, and each one can be a work of art. Can't go wrong with this one.
