Who Installs the New Mosaics in New York’s Subways?

She and many other artists have received a big assist from Stephen Miotto, a master craftsman in mosaics who has a studio in Carmel, N.Y., and the Friuli region of Italy. Mr. Miotto works with artists to recreate their visions in the mosaic tiles; once he and his team of skilled artisans are finished with the assembly, which can take months or more than a year, they press the mosaic into cement-covered substrate in the subway station.
