26 full-page pattern images. They are all single-sided pages to avoid bleeding. If you use markers I would still put a blank sheet between pages while coloring to be safe. All these are original patterns drawn by Twigs Greenpage. This is a perfect present for the colorist in your life. Use markers, pencils, watercolor pencils, gel pens. Meant as an adult coloring book but would be appropriate for a child. If you haven't tried coloring as stress reducer you are missing out. Color yourself to calm. Just relax. It can also be used as a work team-building exercise or a party activity. Look for other Twigs Greenpage titles on the Amazon Marketplace.
