As a German textile artist, she played a crucial role in shaping the weaving workshop of the Bauhaus school. Her contributions were instrumental in transforming the workshop from producing traditional, one-of-a-kind pieces to creating innovative and functional designs for the modern industry.
She soon became a mentor to other students and reopened the Bauhaus dye studios in 1921. After a brief departure, Stölzl became the school's weaving director in 1925 when it relocated from Weimar to Dessau and expanded the department to increase its weaving and dyeing facilities.
Her textile work is thought to typify the distinctive style of Bauhaus textiles. She joined the Bauhaus as a student in 1919, became a junior master in 1927. She was dismissed for political reasons in 1931, two years before the Bauhaus closed under pressure from the Nazis. The textile department was a neglected part of the Bauhaus when Stölzl began her career, and its active masters were weak on the technical aspects of textile production.
