The lines of your coloring page are the rules you need to share with your team, share with them the boundaries. They are more likely to stay with in the lines if they know that they exist. Next by holding the work up for group and team acceptance they become their own self policing force. They can set self expectations and make constructive self criticism as well. The reward is acceptance and recognition from the team, an old saying is that a person can starve without any feedback, but only needs one good compliment to be filled to overflowing.
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.
