[via Laughing Squid] Filmmaker Sarah Gonzalez is producing a documentary on the whimsical phenomenon of yarn graffiti. Yarn graffiti has been cropping up in cities around the world (we’ve recently posted about colorful yarn bombings on trains in Philadelphia and in the potholes of Paris.) Gonzalez is raising funds for the film on IndieGoGo. Check out more at http://yarngraffitidocumentary.blogspot.com/
