Several people, including Betsy and sent me this link to design your own tartan!
Being a Scot, I already have a tartan (and someday I might actually figure out which one it is), but I heartily endorse this. The future is NOW!
I believe the tartan on the left is the Coburg tartan, which Queen Victoria designed for Prince Albert (he of the eternal can imprisonment)
as a consolation for his not being Scots, I mean, as a celebration of his Germanity. Now you don't have to be a queen to make your sweetie a tartan! Click on the image to visit the site.
