People say that ancient textiles were much finer than modern textiles due to handmade properties and cannot be reproduced. I cast that under great suspicion.
I think this is one of those things that gets exaggerated. If you can make one bolt of cloth a year, you’re gonna make it the damn best bolt the world’s ever seen. There’s no real benefit to loosening the tolerances up if you can’t do it a whole lot faster.
But now, can just mass produce it to fully acceptable standards, so why bother spending the extra time to make something that has X semi-legendary property?
