Concerning a method of basketry based on a spirally coiled foundation, esp. that made with a vertical stitch or weft. A basket is said to be coiled when a long bundle of fibrous material is laid up, spiral fashion. Each coil is sewn by a slender splint to the coil below it. The basketmaker would pierce the fiber bundle with a bone awl and pass the splint through the hole thus made. In ceramics, coiling is a construction technique where the vessel is formed from the base up with long coils or wedges of clay that were shaped and joined together.
