Peoples noted for the making of quechquemilts include the Huastecs, the Nahuas, the Tepehuas, the Huichols and the Otomis and the decoration of the garment can identify from which group it comes. However, the climate of the region it is made also has an effect such as the use of wool in colder areas. There is evidence that a number of motifs dates back to the pre Hispanic period. Others were adopted after the Spanish conquest, and a number are hard to date as they show both European and indigenous influence. Ancient designs include fretwork, a symbol for Quetzalcoatl, the scepter of Quetzalcoatl, related to Ursa Major, an “S” form called an ilhuitl and a cross with branches of equal length which represents the cardinal directions. Colors have symbolic meaning such as yellow for east. One European element is a stylized vase with flowers, but the double headed eagle, can be of either indigenous or European origin. The Huastecs in Tancanhuitz de Santos, San Luis Potosí and the Huichols in Jalisco and Nayarit make their quechquemitls in an undyed cotton, which is heavily embroidered with flowers and animals in various colors. The Nahuas of San Francisco Chapantla, Hidalgo and Hueyapan, Puebla decorate their huipils with fretwork, animals and flowers. Among the Huastecs the garment is usually of undyed cotton which is heavily embroidered.
