They're going to be huge for fall, people. Check out Andrea's post on knitted cowls for fall. Of course, the color for fall is grey, but then the cowl can probably be another color.
I have my eye on some Malabrigo Super Bulky, perhaps. Damask or Tuscan Sky for color? Paris Night or Plata for grey? I heart Malabrigo - it's so soft. But there is a downside to the softness: It pills.
But maybe I should find a non-thick-and-thin yarn for this. What about Blizzard? Yarns in the Farms carries it (always a quality indicator), and it comes in a nice heathery grey. My first hats were from this, and I still wear mine, though it gets a little stretchy. Alpaca may not have the sproinginess I'm looking for. What? I say it's a word.
YITF also carries Misti Alpaca Chunky, which also comes in a dark, heathery grey, and is a heavy-worsted, plied yarn.
Blue Sky Alpacas has their bulky yarns, which come in lovely shades, including a grey fox in the naturals that I rather like. But, again, the alpaca may not be the right fiber for this project. And a multi-ply yarn might be helpful, too. I think the cowl should be somewhat crisp.
But I should probably hold off on any decisions until the Lobster Pot Yarns come in. Oops! Was I allowed to tell?
