Don't worry over much about accadentally wearing a "restricted" tartan. Those tartans will be few and far between, and you will not normally find them available for general consumption in any case. Taking a look at the above posted list, when it the last time you saw "Crookdrak-Cheng" listed as available on a retailer's stock tartan list?

Tartans which are truly restricted are going to require custom weaving for the simple reason that the demand for these tartans will be very limited.

So the chances of you "accadentally" wearing a restricted tartan are very slim, indeed.
