Porcupine quill embroidery

Quillwork is a form of textile embellishment traditionally practiced by Native Americans that employs the quills of porcupines as an aesthetic element. Quills from bird feathers were also occasionally used in quillwork.

Porcupine quillwork is an art form completely unique to North America. Before the introduction of glass beads, quillwork was a major decorative element used by the peoples who resided in the porcupine's natural habitat, which included indigenous peoples of the Subarctic, Northeastern Woodlands, and Northern Plains. The use of quills in designs spans from Maine to Alaska. Quillworking tools were discovered in Alberta, Canada and date back to the 6th century CE.

Cheyenne oral history, as told by Picking Bones Woman to George Bird Grinnell, says quilling came to their tribe from a man who married a woman, who hid her true identity as a buffalo. His son was also a buffalo. The man visited his wife and son in their buffalo home, and, while among the buffalo, the man learned the art of quilling, which he shared with the women of his tribe.

Joining the Cheyenne Quilling Society was a prestigious honor for Cheyenne women. Upon entering the Society, women would work first on quilling moccasins, then cradleboards, rosettes for men's shirts and tipis, and ultimately, hide robes and backrests.

Porcupine quills often adorned rawhide and tanned hides, but during the 19th century, quilled birch bark boxes were a popular trade item to sell to European-Americans among Eastern and Great Lakes tribes. Quillwork was used to create and decorate a variety of Native American items, including those of daily usage to Native American men and women. These include clothing such as coats and moccasins, accessories such as bags and belts, and furniture attachments such as a cradle cover.
