British design studio Doshi Levien brings to life in 'Raag' the melodic framework of Indian classical music. The design features a chromatic language of notes woven onto a simple grid background, made of flat fabric in wool and bamboo silk. The multicolor 'Grid 2' runner, for Milan-based rug company Cc-tapis, brings a contemporary, Mid-Century cool to halls and mezzanines. The design can also be used to demarcate space in sizeable rooms.
