The frames of Shoshone cradleboards in the Great Basin were an inverted U-shape. A flat-board was cut into a trapezoid wider at the top than the bottom and covered with native tanned buckskin. Several styles of cradleboards were developed using the U-shape design on the Columbia River Plateau and Northern Plains. Shoshone cradleboards were partially beaded; the Northern Plains cradleboard was fully beaded.
