The Vaughan Welsh Tartan is a historical, family tartan, 
registered with The Scottish Register of Tartans. 
It is also a false tartan.  That does not mean that it is
historically inaccurate, or counterfeit, but that its 
horizontal thread count is different from its
vertical thread count.

The following is the thread count I used to create the
Vaughan Welsh Tartan Wallpaper, so that it would tile 
seamlessly; where I changed the True Threadcount provided
by The Scottish Register of Tartans, I indicate the 
True Number of threads in parentheses.  

I also simplified the color scheme, using G (green), 
W (white), and Y (yellow) instead of Ancient Green, 
Wilson White, Gold, etc.
