So every month The Roots of Design holds a coloring competition where she gives away a design to anyone that wants it, free for personal use only, and you're allowed to enter whatever final coloring you want into the competition. Winners recieve free coloring pages from the Etsy colection, 3 for the grand prize winner/s, and one for each of the runner's up.
If you're interested in joining you can check out https://www.facebook.com/TheRootsofDesign on Facebook to get the page for this month's competition. It doesn't cost you anything to enter, but you get to relax and doodle all over the monthly design, so it's very much recommended.
