Instruction manual for weaving on the Purrington draw-loom, an eight-harness front loom combined with 25 back pattern (draw) harnesses, based on the Swedish "dragrustning" principle. Part I gives the text and explanation of diagrams, covering designing for the draw-loom, warping, threading, tie-up and weaving of four weaves: damask, spot weaves (Swedish lace, spot-bronson), summer and winter, and double weave. Part II contains the illustrative diagrams: harness and pull arrangements, threading drafts, tie-ups, shed diagrams, cross-sections and flat views of the cloth. It includes a foreword by the loom's maker, a preface, and a bibliography of English, Swedish and Finnish weaving books.
