Thoughts on Galicia?

So putting that issue aside, and speaking of woven cloth that has patterns created by stripes in the warp and weft, such cloth exists the world over and is part of many folk traditions.

Not so much. The Igbo patterns here are obviously modern in design and not traditional because they had no such tradition before contact with Europeans. There are 19th century photos of Nigerian warriors wearing European made tartan and striped blankets around their waists.

The same with the Thais, traditional Thai cloth is far more complicated than tartan, I suspect the shawls here also have a European origin. It would be like taking a standard kilt suit today and determining that the old Highlanders loved black jackets and white socks.
