At Chaco Canyon, and in other Great-Pueblo centers, various minor arts also flourished. Feather cloth continued to be made, and still provided robes and blankets for the living and wrappings for the dead. Flocks of domesticated turkeys were kept to provide feathers, and parrots and other brilliantly colored birds were brought from the south. Cotton fabrics were steadily increasing in importance. Some large blankets were woven which must have required the use of an upright loom. Colored yarns were used, and there was some painting of finished fabrics. Variations in weaving also provided decoration. There is no evidence that the people wore any tailored garments, but the remains of a poncho with a slit for the head has been found. There were also some garments of dressed buckskin, in addition to those of feather and cotton cloth. Some sandals with notched toes were woven of fine cord, but this art had degenerated and decoration was less elaborate, both as regards colored and raised patterns. Most sandals were of plaited yucca leaves, and many had square toes. Twined-weaving does not seem to have survived. Coiled baskets were still produced, but they were not plentiful. They were of a finer weave than those of the preceding periods but had fewer colored designs. Yucca ring baskets were extremely common. These were made by fastening the outer edges of a bowl-shaped mat, made of twilled yucca leaves, over a wooden ring. Twilled mats of rushes or reeds, were made in quantity and were widely used as floor and roof coverings. Tubular pipes were made of both clay and stone. These are rarely found whole, and it is thought they may have been intentionally broken—possibly to avoid profanation after use in sacred rites. It was in the field of ornaments that the minor arts of the Chaco people reached their highest development. Olivella-shell beads were still widely used, and there were also stone beads and stone and shell pendants carved into the form of birds and animals; but it was turquoise which provided the material for the finest ornaments. Some beautiful mosaics were made of turquoise, and it was also used in the making of beads. One incomparable necklace found at Pueblo Bonito contained twenty-five hundred beads and four pendants of magnificent sky blue stones.[71] All were shaped and polished with a skill that would do credit to a modern jeweller with all his highly specialized tools. An unbelievable amount of work must have gone into the production of such an ornament when only stone tools were available. Unfortunately we do not have many such specimens—due to the mystery which surrounds the final disposition of the remains of the ancient inhabitants of Pueblo Bonito.
