My friends have ask for a coloring book for them. Adults that work and run as hard as they can all day. They loved coloring but didn't want to color children's coloring books. They needed one of their own. I loved coloring as a child and I love it today. This book is made to draw in and color and you don't have to stay in the lines if you don't want to. If you want to make copies it is ok for class rooms ect. As long as you don't sell them or use them for Commercial sales. These drawings will de-stress you. Make you relaxed and calm. It is so peaceful just sitting and coloring. Each of the drawings is specially printed on a single page with the reverse left blank so you can cut out and use your picture for displaying or framing.
