Come to think of it, I believe I've done Hunting Stewart kilts from Lochcarron cloth that was woven this way. I just didn't give it much thought.

For kilt makers it's actually a perfectly fine way to weave the cloth. It becomes an issue when you intend to do something else with the cloth, like make a waistcoat or jacket, upholster your sofa, or make a banner for the clan gathering, etc. Then you need to be very careful to work around the "hiccup" in the center of the cloth.
