Final answer:
While the question's specific term is not provided in the context, warp-wrapping is a historical textile method unrelated to elastic strip design, and a cylinder seal is an ancient artifact for imprinting designs onto surfaces.
Step-by-step explanation:
The term for sewn elastic strips in a circular pattern that conforms to the head shape is not explicitly defined in the context provided.
However, generally in the art of textile and fashion design, such a technique can be analogous to shaping or constructing an item to fit the contours of the head.
The provided information discusses warp-wrapping and the use of a cylinder seal, which are both historical textile and artifact creation techniques, but they do not directly relate to the assembly of elastic strips in contemporary textile practices.
Instead, warp-wrapping refers to a method where colored fleece is wound around cotton warp threads before weaving to create a design with 32 geometric faces. A cylinder seal is a small object carved in intaglio, often hung on strings of fiber or leather, used in ancient times to roll an imprint onto clay tablets or other surfaces.
