I finished the first Mock Cable Sock back in 2011 on my way home from a UK knitting tour.
The yarn is lovely, Berocco Ultra Fine alpaca and a beautiful heathered colour (1285) including blue and green fibres. Now that I look at the composition of the yarn, I realize it is rather unsuitable for socks because of the lack of nylon content and alpaca wears through very quickly. Whatever was I thinking?
I found the second sock in a UFO pile and noted that I'd already rounded the heel and only needed to finish the foot and toe.
I will keep the leftover yarn as I know I will need to darn these suckers in fairly short order.
