I guess I am in the minority here. I love to color! I prefer the more intricate designs and Mandalas. I particularly enjoy the work of artist Angie Grace and have filled several of her coloring books from front to back. My preferred medium is Sharpie marker, both the fine and ultra fine tip. I do have to use a sheet of cardboard behind the one I am working on to prevent bleed through, but it is worth it as the markers produce the desired results. It is almost unbelievable how many different colors Sharpies come in when you combine the different sets they make! Love to color!!!
