Longest standing and most successful of all Bauhaus enterprises was the Weaving Workshop, whose talented female designers created beautiful textiles, pouring all their energy and talent into this fresh and challenging field of interest. Embracing advanced technology, they used unusual materials (such as cellophane and early synthetics), and made reversible fabrics with acoustic and light-reflecting properties as well as other innovative experimental textiles. Their striking, brightly coloured geometric designs generated renewed interest in hand-weaving and a new professionalism in designing fabrics for mass-production.
