Why do coiled baskets often have radiating designs?

Coiled baskets often feature radiating designs because of the inherent nature of their construction. In coiled basketry, a foundation element is wound in a continuous spiral around itself, starting from a central point and expanding outward.1

This circular, expanding movement naturally lends itself to radiating patterns, such as star- or flower-shaped compositions, or whirling designs that sweep from the center toward the outer edge. While different types of basketry impose their own geometric limitations, the specific technique of coiling provides this unique freedom for designs to emanate from the center of the object.2
