“Yarn bombing, yarnbombing, yarn storming, guerrilla knitting, kniffiti, urban knitting or graffiti knitting is a type of graffiti or street art that employs colourful displays of knitted or crocheted yarn or fibre rather than paint or chalk.” Definition from Wikipedia
Yarn bombing is referred to by some as a RAK random act of kindness.
Part of the fun of yarn bombing is the feel good factor. Spotting a newly yarn bombed street crossing on your way to work in the morning or finding a previously bare tree, down main street, festooned with pompoms. The suddenness with which yarn bombs appear and often disappear is surprising and often magical. Part of the fun of yarn bombing is its gorilla nature. Trying to guess who might have knitted a yarn bomb and where they came from? Were they put there by yarn fairies with crochet hooks or maybe old ladies wearing woolen shawls and knitted balaclavas? Enjoy the magic!
