It's exciting! People seem very supportive. A guy from Keep Indianapolis Beautiful wandered by and said, "Hey, I like your door handle!" The whimsical nature of knit graffiti makes the artist and other people smile. They can't help it.
Finally, whatever you do - don't get yourself involved with a knit graffiti crew; their stuff might make yours look like crap in comparison! I'm serious; I was literally flabbergasted when I saw what some of the other Yarnburners had done; it was immense, and detailed, and beautiful. I was completely unprepared for the quirky, random, thoughtful, colorful spectacle of it all!
