With her face hidden by a balaclava, a member of a rather secretive organisation stands in the middle of a road in County Down. Her codename? Purl 1. Her Age? 47. Her mission? Guerrilla knitting.
Purl 1 belongs to a local group of "yarnbombers" - a movement that creates a special kind of street art using knitting or crochet rather than spray paint.
