Yarn bombing is sometimes labeled graffiti or "guerrilla art." But since its inception -- in 2005 in Texas, according to most internet sources -- it's become more than "a way for crafters to make creative use of their leftover yarns and unfinished pieces." It is "a great way to draw attention to something that otherwise goes unnoticed, like a tree, a statue, or some random street post," says website FeltMagnet or, according to Bella Vistan Debra DeVilbiss, "a celebration of creativity [and] a coming together through contribution."
