My name is Melissa and I am a new member of KnittingHelp. I thought I’d this site because I am across a forum on which wool is warmer Yak, Merino or Alpaca. I recently opened a new organization called Arms of Andes that develops mid layers, base layers, and more from only Royal Alpaca in Peru. I wanted to get feedback from what people thought about Alpaca wool, the benefits and cons. Also, if anyone knows any technical data or studies comparing Alpaca wool or other wools with each other, that would be very helpful.
