The art of coloring is a simple joy. All you need is a coloring book and your choice of tools. From here you can immerse yourself fully into the craft without agonizing about what to make, how to read the pattern, and how will it turn out? Coloring is a a form of meditation. There is something truly hypnotizing that happens with you sit down with a fresh box of pencil crayons, choose the color that jumps out at you and begin your journey into the page. Time loses its grip on the mind and enables the color-er to become present in the moment, in the line and in the color gliding onto the paper.
Well, apparently they were back then and still are today for people of all ages. People are making the adult coloring books bestsellers on Amazon! At the time of this writing, eight of the top twenty books on the bestsellers list, are coloring books for adults. There must be something behind this recent growth in interest.
You can metaphorically take a page out of a coloring book, and break up the work into a few sections. Each team member or group within the team should first be instructed on which part of the page they are going to color, let them know what color they can use, and when their turn will come up. Next, after each team member has finished their part of the coloring than take the completed picture and hangs it up so that every one can see their part of the picture and the entire teams contribution.
