Greetings Kilties!

Since the thread has swung to the fabric process: I’ve got a question. What makes a tartan “old or rare”, and where does the additional cost come into play? Case in point; I want my next Kilt done in the Dyce tartan, which will cost me more than my McDuff modern, if its the same style and from the same maker. Money is tight so I don't see that happening... switching to Plan B.
