Surface couching is the term used to define the basic couching that is done in a way that the fabric thread pops out too in the end result. This is why it greatly depends on the surface fabric like linen, cotton, velvet, and so forth. Among all, cotton is the approved and extensively used fabric for surface couching. You can also use other fabrics with a bit thicker thread as a substitute. Surface couching is mostly used to create outlines, borders, and stems on the edges of bedcovers, curtains, cushions, napkins, and more.
