The tartan is the Bishop tartan and has been registered through the Scottish Register of Tartans. However, it is restricted. I am working with the creator to set up royalties. The link to the tartan info page is here if you wish to look at it more closely:

This single/double width is a bit confusing. Is one preferable for kilts?

And Deil, thanks for the info on the plaids.
