A short instructional leaflet by John S. Fishback on weaving Summer and Winter, issued by Lily Mills as part of Practical Weaving Suggestions. It gives a brief history of the technique and explains the four-thread unit, with a sample warp worked out and three weft methods (singles, pairs, and Dukagang-style repeated treadle). It then covers the sixteen-thread unit with diamond background, with a four-frame chair seat cover and an eight-harness chair seat cover with a central pattern. Yarn specifications, sleying, tie-ups, and treadling orders are included.
