Yummiest. Yarn. Ever.
I recently got myself some Pemaquid (made by The Fibre Company), from Webs. OMG, it feels better than any yarn I have ever laid hands on! It's mostly alpaca, with some merino and soy. It's also partly dyed and partly natural, which makes for very interesting colorways. (I got the Toasted Lavender, which is a pinkish beige with some lavender flecks.)
I only got enough to make a hat, but I am sooooooooooo wishing I'd got enough for a sweater! Then again, maybe I should wait until my sweater skills have improved, as this would be a very expensive sweater. This is one of those yarns whose hanks are both a) expensive, and b) have p00p for yardage.
Unrelated note: If you haven't seen Prime, go rent it now. It's a good movie, but even if it weren't it's worth seeing it just to ogle the knitwear.
