On their website they write:
Knitta began in August 2005, when AKrylik and PolyCotN were discussing their frustration over unfinished knitting projects: half-knitted sweaters and balls of yarn gathering dust. That afternoon, they knitted their first doorknob cozy. Then it dawned on themA A tag crew of knitters, bombing the inner city with vibrant, stitched works of art, wrapped around everything from beer bottles on easy nights to public monuments and utility poles on more ambitious outings. With a mix of clandestine moves and gangsta rap A Knitta was born! Today, Knitta is a group of more than 10 ladies of all ages, races, nationalities, religions, sexual orientationA and gender.What a bizarre and wonderful way to spread a little joy.
