An interesting news article popped up in my news feed today.

As I understand it, the new Balmoral tartan is currently being designed and would be available for the public to purchase. Aside from the usual nonsense about using colours that reflect the landscape and other such fanciful pretexts for the design, there's no indication of what it will actually look like.

The existing Balmoral tartan would, presumably, remain restricted.
