Crayola Crayons

Of Course, why didn't I think to look here before.  Of course Crayola would have thousands of free coloring pages to support your crayon addiction.  They are easy to download and print, they are categorized and they are quality.  If you find yourself wondering how to kill 45 minutes print a few and bring out the crayons.  They even have more advanced versions for older kids like how to draw a horse.
