In the light-washed living room, Karll’s “Untitled,” 1998, hangs over the fireplace. Special dried flowers — hydrangeas gathered in New Harmony, Indiana, on a trip with Jane Blaffer Owen — rest on the mantel. “Her memoir came out last year,” Karll says. “I was pleased that she included a photograph I took of her.” French 19th-century cast-iron table in background. “Sculpture On Ice,” 2016, installed in wall niche.
