Coloring books are a thing of the past. Kids today arent as thrilled by a basic coloring book as children a generation ago. That is because these children have been spoiled by all the fantastic new methods of coloring using the computer or with fancy markers and pens. While you might get away with a coloring book and crayons for a long car trip, dont expect your school age children to sit quietly at the table coloring pictures the old fashioned way - there is a something better around, and they know it.
I was picking out some coloring books for my friends children when she informed me that she would like to get a couple of books too. This is a 30 something year old woman. She then began picking out colored pencils as well with a gleam in her eye like a kid in a candy store. She couldnt wait to get home and start coloring in her new books. She picked Barbie Doll, princess type books and methodically chose what colors she would use for the first picture.
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.
