Since Stacey posted asking about the andean silk, I figured I should post progress, since I've been meaning to and haven't.
Stacey, you can see a version of the Hourglass in Andean Silk on the Knitpicks site if you click here. I really love the yarn; it's beautiful and soft, though if you're put off by slightly furry yarns, this may not be the yarn for you.
These pictures are slightly outdated, as I took them while I was decreasing, with good intentions of posting them, but kept forgetting, got frustrated with the sweater, set it aside and picked it up again since that time. I'm just starting my increases, but here are a couple of shots so you can see the yarn in action!
The color is "sangria".
