Roy Katz. In 2010, Roy and friend Tanya Fleisher began to channel their creative energy into sewing bags and aprons in their Chicago apartment. Turning their passion for art, design, and architecture into tangible goods soon took up more and more of their time, led them into leatherwork, and required heavier machines and more manpower. In 2013 they left Chicago for Denver, and channeled their focus on their business. The pair now own, and are the driving force behind Winter Session - combining traditional methods of craftsmanship with innovative technology to produce beautiful, high-quality, canvas and leather goods in the Five Points neighborhood. They invited me into their workshop last week to photograph.
