Yarn bombing is "a type of graffiti or street art that employs colorful displays of knitted or crocheted cloth rather than paint or chalk." Knitted, crocheted or woven pieces are sewn around inanimate public objects such as bike racks, light poles, telephone boxes & trees. The purpose is to bring some beauty & wonder into otherwise drab everyday surroundings. It is less damaging than painted graffiti & costs next to nothing (a pair of scissors & a few minutes work) to be cleaned up & taken away. Some find it to be pointless & no better than any other form of vandalism, but it can be easily argued that it does cause people to stop & take a fresh look at their surroundings & SMILE.
