Need to relax? Do you have whimsy inside but are forced to have rage? If you do, this coloring book is for you! Works great with marker and colored pencil, however the marker will bleed through, so remove the page first, or use a thicker paper in between while coloring. If you love this book, you can find finished illustrations on products at Redbubble, Teepublic, and Zazzle under Erin Brie Art.
