Yarnbombers Purl 1 (L) and Knit 1 display some of the guerrilla knitting and crocheting which they plan to use when they target next week's G8 summit, in the Mourne Mountains, near Newcastle, County Down June 13, 2013. Yarnbombing uses knitting or crochet work to make a statement in public, rather than graffiti or street art. REUTERS/Cathal McNaughton (NORTHERN IRELAND - Tags: BUSINESS CIVIL UNREST POLITICS SOCIETY)
