I just want to note here that if you are ordering a Irish county tartan, be aware that there are 2 mills, House of Edgar (HoE) and Marton Mills (MM), offering different tartans for the counties, as well as 2 "national" tartans and other various setts. They are quite different, most of the HoE tartans tend to be more 'earthy' in their colors, while the MM tartans are based on the "County Crests" of the various counties, and are more vibrant.
So don't just tell a kiltmaker "County Waterford"and forget it! Aviod suprises and be sure to specify the mill, or better yet the STA number, of the tartan you want.
