Berta Frey describes a hand-manipulated leno (gauze) technique inspired by Peruvian and Guatemalan weaving, worked without doups on an ordinary twill-threaded loom, and it also works on two harnesses. She explains how to pick up and twist warp threads by hand, how to plan designs in units of two squares, and how to lay in pattern blocks, comparing the method to the Spanish 'Red-de-Telar' loom-net. Examples include a fish motif from a tapestry belt and a llama design after D'Harcourt, shown in a sampler photographed in two illustrations and in four figures.
