The thin embroidery threads are worked in zig-zag lines with a small loop around the intersection of the ground meshes, at the top and bottom of the triangles that are being created. Sometimes a second zig-zag line is worked parallel to the first, creating a series of irregular diamonds. They are applied inside the outlines of the individual motifs and are thus filling in the motifs.
This type of embroidery was carried out by people of the Chancay culture in Peru and dates from about 900 – 1430. The Chancay people lived in various valleys along the coast of central Peru. The production of ceramics and especially textiles, including embroidered cloth, was an important part of Chancay life.
