Chocolate argyle socks, actually.
I couldn't think of any contrast colors to go with the original sage-y green color of the yarn, so I dyed the socks after knitting. I used about 2 g (eyeballed, not weighed) of Jacquard acid dye in 'brown' to get this shade.
I got started with the duplicate stitching following these instructions. Originally I'd used a dark pink for contrast but it was too bright and went instead with the French blue Rio de la Plata sock yarn, and the original un-overdyed yarn. The sock yarn is a cashmere blend yarn from China and was a generous gift from Maryann. The yarn is a bit inelastic, so these might end up as bed socks sooner than later, but my, what luxurious bed socks they'd make!
Mods for these socks include using thinner yarn with 2.25 mm needles (pattern calls for sportweight yarn to make 'man' sized socks), and knitting a half repeat less than called for because I was afraid I'd run out of yarn (I didn't, boo.) If you look closely at the ribbing, you might see that the dye didn't get into every nook and cranny, but you're not going to look closely, right? :-)
After knitting five pairs of socks in a row, I might take a short sock break. However, I feel absolutely no guilt getting some new sock yarn.
From left to right, Shibui sock yarn in peacock and mulberry, and Araucania's Ranco sock yarn.
Chameleon Colorworks' Evolution in Eggplant, Handmaiden Casbah in brick (both so incredibly soft that I don't think I'll make socks with them), and Dream in Colors' Smooshy in Gothic Rose, which has been wound into a cake. It's a huuuge hank and I wonder if I can squeeze a pair of knee socks out of them.
After seeing Polly weigh her sock yarn with some surprising results, I thought I'd check mine too. I'm happy to report that with the exception of the Chameleon Colorworks yarn, which came in at 2-3 g under the stated weight, all the other skeins are over, in Shibui's case 10%, the stated weight. Isn't it nice to get bonus yarn?
