Yarn Bombing is a type of street art created by knitting or crocheting blocks of yarn around trees, sculptures, lamp posts, signs or other outdoor fixtures. Yarn bombs or yarnstorms, may last for years, they are considered non-permanent, and, unlike other forms of graffiti, can be easily removed if necessary.

While other forms of graffiti may be expressive, decorative, territorial, socio-political commentary, advertising or vandalism, yarn bombing was initially almost exclusively about reclaiming and personalizing sterile or cold public places. It has since developed with groups graffiti knitting and crocheting worldwide, each with their own agendas and public graffiti knitting projects being run.

The Kingman 2013 Yarn Bomb was a project of Kingman area knitters and crocheters who gather at The Spinster shop in Kingman, Arizona. It was set up at the Kingman, Arizona Railroad Depot.
