There must be adequate proof of weaving of a tartan to be recorded. The best evidence is a woven sample showing the full set. Please send a sample to the following address:
Scottish Tartans World Register Tartan Administration, The Glack, Dunkeld, PH8 0ER, Scotland (UK)
Tartan is controlled by social convention and in many cases with informal agreements between weavers etc. The Register will record these arrangements in the interest of convention and to help in the smooth running of the tartan trade.
