sett

Alternative spelling: set. This term is used to indicate the density of the ends and picks in a woven fabric.  Usually expressed by the number of ends per inch or centimetre and the number of picks per inch or centimetre.  For example a square sett cloth would have the same number of ends and picks in a square inch or centimetre.  The state of the fabric should be described at the same time, for example: loomstate sett or finished sett. Sometimes the term pitch is used to mean the same. See tartan.
