Kid's are fearless. Yes they can get nervous, aren't sure of themselves, or may be a bit timid towards art, but at the end of the day, when you put a brush in one of their hands, they will paint. They will blow you away with their raw creativity, because they just go with it. I may have blabbered on for a few minutes about the project, but they'll take it with a grain of salt, and have fun with it. And isn't that what art-making is all about?
