All I know is that mine had a length of Bear tartan that was a little wider than single width and everything on past the width it was supposed to be was reversed or something like that, and had a dividing line of some sort. He made a kilt out of it and was making a second kilt, so the tartan was fine on the part below the dividing line.

Haven't seen Mein on the forum for a week or so, but he might be interested in this.
