Well, here are mom's socks, on my feet:
I used, in total, slightly less than two balls of Louisa Harding Kimono Angora in color #4, and somewhat less than 3 balls of Elann's Baby Cashmere in "Claret," knit at 6 stitches per inch on size 3 double-points.
The pattern comes from the sock book shaped like a sock; I don't remember what the pattern is called, as I have already returned the book ton its owner :-).
It's got a subtle windowpane texture which is lost, visually, in the variegated yarn, but trust me: it looks nice in 3D.
The Kimono Angora is 70% angora, 25% wool, 5% nylon; the Baby Cashmere is 60% baby alpaca, 30% merino wool, and 10% cashmere. I guess that makes these socks 35% angora, 30% baby alpaca, 27.5% wool, 5% cashmere, and 2.5% nylon. Easily the most luxurious socks I have ever had on my feet. I love them, and I have been well-bitten by the sock bug. I think I will make socks for my dad for Christmas, too, in 100% cashmere, as he is a cashmere junkie.
I love the Kimono Angora, by the way: it is soft and fuzzy as angora should be, but it doesn't have the shedding I associate with angora and, most importantly, it doesn't itch. I'm not joking: I stuck my swatch inside my bra for a few hours and didn't notice it at all. Normally if I put something with angora next to my skin, it itches like crazy. This is a great tragedy for me, as I adore angora. But I can wear Kimono Angora! I only wish it weren't so darned expensive; I'd make a sweater out of it.
Maybe I can afford a Kimono Angora bikini :-).
