1. Did you try amazon? Check whom they get yarn from. I’ve gotten all kinds of natural yarns angoras and whatnot through thm.
2. There are yarns that have glittery threads in them that are wool or cotton. My daughter has a soft sweater like this.
Hope you get good responses.
I’m under the impression that the yarn weight gets in the way as far as the more hobbyist specialty yarns. This is being run as a pattern in 30/1 cotton with lycra on Italian circular knitting machines.
Thank you so much for responding and wishing me well with this, though.
