Every color but blue is represented -- and I still don't know why it's called Christmas balls, but I sure would like to see the color namer's tree.
Here's something interesting that happened with this sock. See how it looks as if I intentionally managed the colors so the first inch would have that distinct straight edge, after which the colors begin spiraling? It had nothing to do with any planning or manipulation -- that's what happened when I had to interrupt my knitting to accommodate the first knot in the skein. It's fascinating how the simplest thing can affect the way the colors fall. I suspect that once I do the heel flap and pick stitches up again for the foot I'll get yet another change in patterning.
I'm using a slip-stitch rib for the leg -- very stretchy, and fun to do. One row is k3, p2 all the way around; the second row is k1, slip 1 as if to purl, k1, p2, and follow that all the way around. The picture above shows the sock unstretched, as it looks while I knit. See how the slipped stitches emphasize the column effect of the ribbing? I especially like that section where the white is dominant. And here's what it looks like when stretched out, as if being worn:

Tonight the heel. . .
