Homemade Sidewalk Chalk

This one's for those with kiddies - homemade sidewalk chalk! I love chalk. I've loved it since I was little. And I know, it's fairly cheap to buy at the store. But what if you want a color the store doesn't have? Or you want to make multicolored chalk, but don't like the mixes at the store? Or better yet, you hate the size of the chalk - they are so small, and run out fast! My plain is to make chalk. I hope that when we finally have kids I'll be able to be the awesome, artsy-fartsy mom that does stuff like this. *Here's to hoping!*
As with all of my posts, the picture is a link to the tutorial, as well as the link below it.
