Step 4: Disclaimer
Now there is presendence of chalk being labeled by a court ruling to be a non-destructive medium in the Josh Kinsberg Bikes against Bush case, so feel free to use liberally with the color caveat in mind. It dries fairly quickly, and the clean up is minimal, but as always people might jump to conclusions based on how you decide to apply the medium, so make sure that you don't look like your doing anything illegal, especially if you are.
Lastly, don't feel limited by the content depicted in this instructable, be creative, have fun, be careful.
