spiral coiling

Spiral coiling is a basketry technique where a foundation of a single element is wound in a continuous spiral. This spiral is held together by a thread, with work progressing stitch by stitch and coil by coil. This method is prevalent in temperate regions, northern Eurasia, northwest North America, and parts of the southern Pacific.12

The nature of the foundation element influences the appearance. If the foundation is solid, the thread binds each coil to the preceding one, creating a diagonal or twilled effect. If the foundation is made of multiple strands, the thread catches one of the preceding coil's strands with each stitch. This technique allows for various aesthetic effects, such as smooth or rough surfaces and color contrasts, depending on the materials used.21
