There are two terms that "Coyuchi" refers to. The first is the Oaxacan word for naturally colored brown cotton. Originally derived from the Aztec language, it refers to the color of coyote fur.
The second, is the Oaxacan word for white or brown cotton from the Oaxoca, Mexico. Coyuchi was spun using a slender rod, or malacate, then woven into fabric on a back strap loom. The resulting fabric was either white or dyed with colorful designs using natural dyes from cochineal, caracol, añil and other plants.
