The Glasgow tartan can be dated with certainty to the beginning of the 19th century. Full details of the pattern appear in Messrs Wilson of Bannockburnas 1819 Key Pattern Book, but it also appears in Wilson papers dating from 1800. The pattern lay dormant for many years until it was revived in the 1960s. Wilsons are known to have applied the names of town and cities to patterns where they sold well, or had been obtained from. No other reason can be found to link the pattern with the place. Present day usage defines this as a "district" pattern, suitable for use by persons having links with the place, or as a momento of their visit.
Size will vary depending on sett size, pattern repeat and type of fabric.
