A coiling market basket refers to a basket made using the coiling technique — one of the oldest basket weaving methods. In coiling, a core material (like grass, straw, raffia, pine needles, or even fabric) is continuously spiraled and stitched together with a more flexible thread, such as yarn, raffia, or sinew. Each round is built on top of the previous one, allowing you to create beautiful, sturdy, and often quite intricate baskets.
