gimp

Gimp is a narrow ornamental trim used in sewing or embroidery. It is made of silk, wool, polyester, or cotton and is often stiffened with metallic wire or coarse cord running through it. Gimp is used as trimming for dresses, curtains, furniture, etc. Originally the term referred to a thread with a cord or wire in the center, but now is mainly used for a trimming braided or twisted from this thread. Sometimes gimp is covered in beads or spangles.
