Mary, the yarn for the socks is Online Circle Color #1055. I got mine from Simply Sock Yarn, they have it on a really good sale right now. (I paid more than that, I think. I bought it a couple months back).

I also think I've found a pattern for that green and black sock yarn (well, now it's GLOVE yarn...). I want to try Nereid, provided it doesn't fight too much with the color patterning. I'll have to try it and see. If that doesn't work, I may either do just plain gloves, or do some kind of zig-zag lace, like the one sock pattern in that Handpainted Yarns sock book.
