Guerrilla Crochet

Yarnbombing, yarnstorming, guerrilla knitting, urban knitting or graffiti knitting is a type of street art that employs colorful displays of knitted or crocheted yarn rather than paint. They are considered non-permanent, and, unlike other forms of graffiti, can be easily removed if necessary. Nonetheless Yarnbombing is still technically illegal but it’s not often prosecuted.
