Tartan is a pattern consisting of criss-crossed horizontal and vertical bands in multiple colors... the ‘sett’ which is repeated over and over again until the desired length of cloth is produced. Early tartans were simple checks of perhaps only two or three colors..then with the evolution of chemical dies, weavers were able to introduce more elaborate patterns including more vivid and varied colors. Tartan was used to make the items of clothing which are today considered traditional Scottish dress, including Kilt.
