chattan tartan

[creagdhubh]

Is the sett size on the chattan ancient tartan bigger than the modern? Or are they the same large sett size?

I think much depends on the mill who weaves the tartan. As far as stock ranges of the Chattan tartan are concerned, it appears that Lochcarron's Chattan tartan in the ancient colour scheme (which is the only Chattan variant they offer) has the largest sett I've seen. Of course, when going the custom weave route (D.C. Dalgliesh), one could enlarge the sett size accordingly.
