Native Americans stored their buckskin clothing in tipi bags. They are also called "possible" bags, since such containers could store any possible item. These bags are made of tanned buckskin in a rectangular shape with the lower portion slanting inward. Pieces trimmed from the lower portions were often left intact to become dangles on the bottom corners.

Early tipi bags were porcupine-quilled, usually with lanes on the front. In later times the sides were beaded, which aided to keep the bag open. Most have horse hair dangles on the sides and fluff feathers on the quilled lanes. Many have ties in each corner of the possible bag to hook over the front and back of a woman's saddle. Tipi bags are usually made in pairs, so the horse appeared balanced with an embellished bag on each side of a saddle.
