On a recent stash enhancement visit to Koigu, I got a bag of uncolourful salt and pepper, KPPPM #312.
I typically think of Koigu in terms of brilliant colours, but after knitting some commercial salt and pepper yarn I decided to try something similar in a pure fine merino.
This is a size Medium pair, knit with 72 cylinder and 36 ribber on the Verdun 47. I've done a 1x1 top and 5x1 leg and instep. The heels and toes are reinforced with a grey wooly nylon.
