Ah ha! I have finally finished one sock from the ever-challenging Socks That Rock. And it only weighs 55g, so I should have more than enough for the second sock, as the skein is 120g. What a relief.
People keep asking, I keep ignoring them; the stitch pattern is from the Vogue Stitchionary, vol. 1. I highly recommend this considerable tome to those of you who enjoy making up your own socks. There are MANY viable options provided in this book. The Socks That Rock are in the colorway Cobalt Bloom.
