A pair of socks for my friend's brother. I wasn't sure what the yarn would do, and it turned out to have such a strong pattern that I can't say it was really appropriate for the knit pattern I put into it (a purl-slip-purl pattern which is almost invisible here, and a pattern of yarnovers) but it at least kept the knitting more interesting, and it sort of works. :) I have yet to make a really "plain sock," I always tend to want at least ribbing, and usually go with a seed stitch ribbing.
One thing I'm noticing is that while we can get some fun sock yarns here (mostly made for export, with us getting the dregs), they all seem to have pretty extreme color changes; nothing very subtle. And if you want to do patterned knitting and not have it compete with the yarn's striping, it needs to be a bit subtle. I actually got several inches into a skyp sock and decided the yarn's color made the pattern almost invisible and the pattern detracted from the yarn's pattern, and frogged it (to the protests of my friend Berfin, who likes everything!). So I'm trying some of my own dying now and will share one example soon.
