This is a lovely sock with interesting architecture. It is worked toe up with the increases for the heel being worked in a lace chart insert. The lace then curves around your leg and meets in the back.
The sock is offered in one size, but you can make it bigger or smaller by changing your needle size.
This pattern was originally offered in the e-Book “The Sock Report, vol 1, summer 2012” from Rustling Leaf Press, which is now out-of-print. It is still available directly from the designer.
