Sock knitting returns:
Yarn is Cherry Tree Hill in Nantucket Red.
The color is less intense than pictured.
Figures, as the alternative picture was too washed out.
Discovered this Mystery Sock KAL at Ravelry. The pattern and knitalong are crafted and hosted by Through the Loops.
I'm on the cuffs. Not enough visual here to serve as a spoiler, though I'm happy to report I'm much further into the cuffs than pictured here.
