Brooklyn Creative Studio bestows do-it-yourselfers with the skills needed to make their own bath and body products. Its classes, held at different times throughout the week, include all supplies needed to make a signature face cream, lip balm, or soap. The studio purveys shea butter that’s unrefined and imported—like a Canadian lumberjack living in SoHo—and it also offers an array of specialized oils, such as body, perfume, and massage oils.
