ScareHouse, one of Pittsburgh's most famous haunted house attractions, has earned national press, and praise from fantasy-horror director Guillermo del Toro. We talked to a leader at ScareHouse: Design manager Nicole Conniff, who started at the house in 2009 as a makeup artist and actor. She's also a longtime vendor at the Pittsburgh Renaissance Festival, where she sells her own custom masquerade masks, terrariums and candles. We asked her how she works.
