Bouclé

Bouclé isn't defined by its weave so much as by its yarn. Bouclé yarn is spun with a looped, curly texture, made by twisting two yarns together at different feed rates so one wraps around the other in small loops. That yarn is then woven or knit into a cloth with a nubby, textured surface, most associated with the Chanel-style tweed jacket, though the term covers a wide range of looped and textured fabrics.

The looped yarns make bouclé prone to snagging and raveling at a cut edge, so seams usually need binding, a serger, or a lining to keep them from fraying apart. It doesn't press flat the way a smooth wool would, since the texture is the point, and pressing too hard crushes the loops. It has body and some structure but little drape, and most bouclé garments are underlined to help the cloth hold its shape and to keep the loops from pulling from the inside.

Bouclé is a jacket and coat fabric first, prized for its textured, tailored look without needing a heavy interlining. It also appears in skirts, cardigans, and as a trim fabric on collars and cuffs. Because of the fraying and structure issues, it's a better project for someone who has already sewn a few structured garments.
