Can you be a bit more specific in what you need? That will help us guide you.

Do you know which weaving mill you prefer and which weight of fabric you prefer?

And there are kiltmakers in Maine. At least one is a member here.

But if you want fabric for table coverings or for making stuff like banners, may I suggest that you take a look at one of our advertisers. Burnett's & Struth. They are located in Barrie, ON Canada but stock perhaps one of the largest inventories of Tartan fabric in N. America.

You may also buy fabric direct from all the mills. Each will have a slightly different set of dyes so the colors will change a bit.
