My second Kami hat knit in Lang Yak. I’ve said it before, and I’ll say it again, Lang Yak is my all time favorite yarn. While it’s not cheap ($14.50), the yardage is pretty good, 142 yards. I can knit a Kami out of one ball and still have yarn leftover. This yarn is SO warm, and it wears amazingly. I wish I could find my purple Kami, because it’s a great example of how well the yarn has worn over the last few years. No pilling. Ravelry project page here.
