Artists looking for public spaces to create larger-than-life drawings often run into a maze of bureaucratic red tape. But artists Erica Duthie and Michael Townsend of Rhode Island have found a way to get around that problem by literally using tape to sketch out their landscapes and murals on concrete walls, buildings and other surfaces. This week, Duthie and Townsend have been sharing their tape technique with students at Marcy Open School in Minneapolis. Duthie says tape art is an ideal medium for kids who want to express their artistic interests in an environmentally friendly way.
