 Under the direction of Gunta Stölzl, the workshop experimented with unorthodox materials, including cellophane, fibreglass, and metal.From expressionist tapestries to the development of soundproofing and light-reflective fabric, the workshop's innovative approach instigated a modernist theory of weaving.Former Bauhaus student and teacher Anni Albers published the seminal 20th-century text "On Weaving" in 1965.
