Half the beauty of street art is stumbling upon it in an unexpected place, on the wall of an old factory, or the corrugated curves of a metal gate. Joseph Carini has moved street art to an even more surprising spot–underfoot, in carpets he designed. Like another creative rug designer we featured this month, the Brooklyn-born artist has applied his modern tastes to a traditional trade, by collaborating with 20 street artists to create 50 carpets hand made by artisans in Nepal. The collection, called Back Against the Wall, is in the Carini showroom in Tribeca, and features well-known Brooklyn and NYC street artists like Peru Ana Ana Peru, Dain, and Cost–most of whom will never see their graffiti woven into tapestries again. It opens tonight.
