Nellie Sargent Johnson describes an experimental eight-harness twill sampler woven by her student Helen Hill, using 20/2 beige cotton warp sleyed at 2 per dent in an 18-dent reed, with No. 10 mercerized cotton weft. Page 1 gives a combined threading draft of six twill variations (780 warp threads, threaded to a center and reversed) and an explanation of each section. Page 2 offers six more threading drafts, giving 12 alternative threadings, plus fourteen numbered tie-ups and an explanation of how to read them for Structo, jack, and rising-shed looms. The sampler produced about 176 different weaves.
