An essay by Anni Albers on the approach to teaching and practicing handweaving at Black Mountain College. She argues that handweaving and machine weaving share the same constructive process, that handweaving should return to fundamentals and experimentation rather than traditional recipes, and that it can serve as preparation for industrial production. The article is illustrated with photographs of student work from the college, including drapery materials, a double-weave wall hanging and a tapestry, plus display material by Albers.
