A short instructional article on creating patterns by plying two or more colored yarns together with different twist directions and pitches, used as weft (and in principle warp). It defines five twist types (zero, slow right/left, fast right/left), explains how to prepare them with a spinning wheel, doubling stand and warping frame, and gives a tie-up for a sampler in tabby, 3:1 biased twill and broken twill. It lists nine sample weft sequences and notes on extending the technique to more colors and to warp twist.
