Technically, because the designs are embroidered onto the background and not woven into the fabric, the Bayeux Tapestry is actually an embroidery and not a tapestry. Among pictorial cloths of this scale, tapestries are far more common than embroideries, as the tapestry is woven on a loom while the process of embroidering stitch-by-stitch usually lends itself more to small-scale works. Because of this, many people have come to associate the term tapestry with all large scale pictorial cloths whose design is carried out by thread, without realizing the difference between the threads being part of the woven fabric versus being embroidered onto an already existing cloth. In the case of the Bayeux Tapestry, the term was incorrectly applied because of this lack of distinction, but it has been retained largely for the sake of tradition and its popularity.11 R.
