This year, Ellen DeGeneres, in collaboration with HGTV, made a splash in the design world with Ellen’s Design Challenge, which featured six aspiring designers jockeying for a grand prize of $100,000. We welcome Katie Stout, the winner of the competition, and her carpenter, Karl Champley, for a discussion with Dwell Editor-in-Chief Amanda Dameron, who was one of the judges on the show. Join the group at Stage A at 4:00 p.m. on Saturday.
