I'm guessing the techniques Master Kiltmakers use are the old traditional ones. I know I've heard/read some distain for "tailored" kilts from kiltmakers trained in the old traditional ways.

I'd have no clue. Visions of a traditional kiltmaker and a tailored kiltmaker comparing techniques.

But I'm near certain that someone who earned the designation of Master Kiltmaker would earn it by demonstrating knowledge of the old ways of kiltmaking.
