I just finished a pair of socks from Regia Silk Color yarn, which is 20% silk, 55% superwash wool and 25% nylon. It is marginally more difficult to knit with, because it is not as elastic as the standard 75% wool yarn, but has a very soft hand. The socks are for my son Ian's girlfriend on the occasion of her graduation from University of Washington. Since I finished these, I started a pair on Opel yarn, 75% superwash wool. They seem very stiff and harsh compared with the Regia silk. I hope I haven't become addicted. What would I do with my Opel stash?
