Here are the latest socks from my collection of disappointing silk skeins. In the early 1990's I found several discounted skeins of "Grainy Silk," from Rowan yarns. They formed a series of different intensities of indigo dye, and I thought surely they'd make a lovely, subtly-shaded Fair Isles sweater vest. I swatched and swatched, but the yarn has no elasticity at all, and stranded knitting looked and felt quite dreadful.
Cables and twist-stitch patterns were equally unsuccessful. The only viable choice for patterning seems to be knit-purl patterns. I fell back on this "Pennants" pattern, which behaves as a ribbing, making the socks a little more flexible.
The afternoon sun makes the socks look black, but these skeins were actually the darkest of the indigo series.
