Coiling is one of the oldest documented methods for constructing baskets. Unlike plaiting or twining, coiling builds a basket by winding a continuous bundle of foundation material in a spiral and fastening each new coil to the previous one with a binding element. The resulting structure is dense, often rigid, and particularly suited to holding fine or dry goods.
Structure of a Coiled Basket
A coiled basket has two primary components: the foundation and the binder. The foundation is a thick bundle or rod of fibrous material — typically grasses, cattail leaves, pine needles, or rush — that forms the spiralling core of the wall. The binder is a narrower, more pliable strip that wraps the foundation and passes through or around the preceding coil to lock the layers together.
The starting point is almost always the base. Weavers form a small tight knot or loop, then begin wrapping the foundation into a flat spiral, stitching after every quarter turn. As the spiral grows, it is gradually curved upward to form the walls of the vessel.
Common Stitch Types
The choice of stitch affects both the structural integrity of the basket and the surface texture. Three stitches appear most frequently across documented traditions:
- Lazy squaw stitch — The binder wraps the new coil several times before anchoring once into the previous coil. Produces visible horizontal wrapping across the surface.
- Mariposa stitch — The binder passes under the previous coil and splits back over it in a figure-eight pattern. Creates a knotted appearance at each anchor point.
- Figure-eight stitch — Each wrap travels between the current and previous coil in alternating directions. Results in a tight, closed surface.
The Smithsonian Institution’s National Museum of the American Indian holds documented collections of coiled baskets from multiple North American traditions, including examples that illustrate variations in stitch technique across regions. See: americanindian.si.edu
Foundation Materials Used in Canada
In Canadian traditions, the choice of foundation material reflects what grows locally. Sweetgrass (Hierochloe odorata) is widely used in eastern Canada, particularly in Mi’kmaq and Haudenosaunee work, where it is both the foundation bundle and part of the decorative overlay. Its distinctive scent persists in finished baskets for years.
In the Great Plains and the interior of British Columbia, bulrush (Scirpus species) and tule reed are common foundation choices. Cattail leaves, dried and softened by soaking, appear frequently in Anishinaabe basketry from the Great Lakes region.
Maintaining Tension
Consistent tension is the central skill challenge in coiling. If the binder is pulled too tightly, the base will dome or the walls will lean inward. Too loose, and the surface becomes uneven and gaps appear between coils. Experienced weavers describe finding the correct tension as a physical memory — something calibrated over hundreds of hours of practice rather than measured.
When working with dried grass bundles, weavers often keep the material slightly damp to maintain flexibility. A wet cloth or damp towel placed over unused foundation prevents cracking during work sessions. Splitting and breakage in dried material is one of the more common frustrations for people learning the technique.
Pattern and Colour
Colour patterns in coiled work are introduced through changes in the binder material. A weaver might switch from undyed sweetgrass to a bundle dyed with walnut hulls or ochre to create geometric bands, diagonal lines, or repeated motifs. In many Pacific Northwest traditions, pattern placement encodes meaning — certain arrangements are associated with specific families or ceremonial contexts.
Patterns in coiled basketry are rarely decorative in isolation. They record relationships, mark ownership, and communicate belonging within a community.
Finishing the Rim
The rim of a coiled basket requires careful finishing to prevent unravelling. The most common approach is to wrap the final coil more densely than the body, then tuck the end of the binder back through the previous row using an awl. Some traditions add a separate rim element — a twisted cord or a strip of pliable bark — that is bound over the last coil to create a clean, reinforced edge.
