There is not much I can say about the Skew socks that hasn't been said before.
With this pattern, normal striped yarns do crazy wild things.
Knitting the heel involves a huge leap of faith - even now, after having knitted two of these heels, I'm not quite sure how the turn occurred:
And I'm very good at maths!
After the heel turn, a bunch of short rows are done so that the knitting is straightforwardly in the round again. It was very clever!
I love my new, crazy socks (yarn: the appropriately titled Opal Crazy in colourway 1901).
