Think about it this way; would you rather spend about an hours looking over and printing out SpongeBob coloring pages, or would you prefer to drive all over the place looking for a SpongeBob coloring book? The answer to this really depends upon whether the website, or websites, you are visiting have the coloring pages of SpongeBob Squarepants that you really want. Chances are that the website/websites that you decide to look on will have the images that you are looking for; yet you might not always find what you are looking for out there. Do you realize that you can have as much fun looking for the SpongeBob coloring pages that you want as you will when you sit down to actually color those pages?
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.
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.
