An article by Suzy Sewell, the last in a series on the Peruvian textile collection of the Science Museum of Minnesota. It describes the structure and materials of ancient Peruvian tapestry: cotton warp, fine wool weft, very fine setts, and slit, dovetailed and interlocked joins, illustrated by two diagrams. It also covers design (animal, humanoid and geometric motifs, diagonal arrangements, tessellation) and finishing details such as tassels, woven tab fringes and warp or weft loop fringes. Photographs of museum pieces and a bibliography of Peruvian textile sources are included.
