This is a fascinating subject. It shows how the practicalities of business make minor adjustments to the theoretical practices to produce the wide variations, even uniqueness, in the world of fabrics.

Even more amazing in this particular discussion is the gathering of the original players - that is, Gordon wove the other sample. That also happened when he saw one of my kilts made from tartan of unknown origin - again, unknown until he saw it and pointed out some of the manufacturing elements that identified it as woven by F & K.

This forum is indeed a "gathering" place.
