I made a sock!
I mean: it is far from being the perfect sock. The yarn is scratchy, and I don't like multicoloured yarn, and I'm pretty sure my feet don't end in a central point, and I unravelled the whole thing immediately after taking this picture - but I am still more pleased with this little beast than with anything else I've ever knitted.
It's just such a miracle! For pretty much everything else, you knit rectangles, or tubes, and stick them together to more-or-less successfully cover your body. But socks! You start with a tube, you go off in a different direction, you pick up stitches, you start a new tube in a different direction... and, magically, you end up with something that is the actual shape of a foot!
Truly, a triumph of ancient engineering.
