I designed these socks on a cold winter day in March 2018, so the name of the socks comes from the timing but also from the cold colorworld of the socks. The turquoise and petrolium parts are made with leftover yarn the same strength as the black and the white.
First of all: I’m sorry about a bit blurry pics. For some unknown reason I just can’t get a good shot (I’ve tried ten times maybe). Anyway, Underworld looks difficult but actually it’s easy to knit. You don’t have to purl any single stitch!
