Awesome Colorful Examples of Yarn Bombing

Nowadays knitting can hardly be called a grandma’s hobby. Since 2004, it’s been developing into a new street art phenomenon – yarn bombing (or yarnstorming, guerrilla knitting, graffiti knitting and even grandma graffiti). It employs colorful knitted and crocheted yarn or fiber on different displays, such as hydrants, lampposts, mailboxes, bicycles, cars or any other ordinary urban objects. Though these yarn bombs (or yarnstorms) may last for years, they are considered non-permanent and technically illegal.
