What's with this fabric?

[Iolaus]

I take it that this is wool?

This is all it says:

This auction is for 3 1/2 yds of wool. It is plaid mostly williamsburg blue with red, some black and white. It has stamped on Made in Scotland . My mother in law use to do a lot of sewing and had a man bring several pieces from Scotland for her.This was one of them. It is 62" wide. A very nice peice of material.
