Thank you all for participating, a variety of sock yarn experiences for sure.
The winners, provided by my son's new-for-high-school graphing calculator's random number generator are the first Elaine (Elaine, are you the Elaine I know who used to keep a blog? Let me know) who will get the set of mini-skeins and QueenMeadow, a homeschooling, running, knitting blogger in Utah who will get the hard to photograph but lovely red skein.
Thanks all for the thoughtful comments. Funny how different people have different experiences. For me, the best socks have been my Koigu ones. I've machine washed and dried them repeatedly. They did fade a bit but have held up well. I don't have any holes in any hand-knit sock yet, but really I got my sock-knitting groove started last spring and I don't wear socks much in the summer. This winter will be the test.
I did get ideas though. Treesh's comment about long staple wools made me think of some fingering corriedale I purchased for lace. But the lace I made with the first skein doesn't stay blocked, it's too springy. Perhaps the second skein wants to be socks? Won't be superwash, but might make some comfy stretchy socks.
