In embroidery, couching and laid work are techniques in which yarn or other materials are laid across the surface of the ground fabric and fastened in place with small stitches of the same or a different yarn.[2] Laid work is one of two techniques used in the Bayeux Tapestry, an embroidered cloth probably dating to the later 1070s.)[3] Underside couching of metal thread was characteristic of earlier Opus Anglicanum in Medieval England and was also used historically in Sicily and rarely in other parts of Italy and France.[4] Couching is also characteristic of Japanese metal-thread embroidery and Central Asian suzani work.Another example of Islamic embroidery is the strong tradition of couching stitch in Palestine.
