This is not just a coloring book... in fact when I first bought this 'book' 10 years ago, I saw it more as a craft project. Inside the cover, you will find beautiful, uncolored reproductions of Louis Comfort Tiffany's stained glass artwork on a resiliant, translucent plastic 'paper'. The designs feature birds, flowers, and trees from some of Tiffany's most famous works. Sure you could color them and leave them in the book- but why? What I did was use a little adhesive and used one design to cover the 8.5 x 11 inch windows flanking my front door. They are beautiful colored or not. I get so many compliments I have people asking how I did what I did and where they can find the book! This book is pure artistic delight! Other stained glass designs are available as well. I'm buying more.
