In the post-war era, Bernat Klein became internationally renowned as a designer of textiles for both fashion and interiors, primarily for his accomplished use of colour. This paper will extend my previous research on Klein’s practice as a consultant designer of furnishing textiles and carpets. It will also explore the visual and technical relationships between his textiles for fashion and those for interiors. The presentation will include an investigation of the key characteristics of Klein’s design consultancy work in Britain and Scandinavia, which mainly related to furnishing textiles and carpets between 1966 and 1980.
