Cuff: Regia Extra Twist Merino in black. (I bought only 1 skein of Regia 4-ply in black and I’m pretty sure this won’t be enough, hence I use the Merino as an additional leftover just for the cuff.)
CO 64 sts
Ribbing: 20 rounds.

Changed to Regia 4-ply in Black, started chart, knitting only 4 sts (instead of 5) between the fishnet parts, like so many other knitters.

I like the slip stitch sole pattern very much, it is a corresponding equivalent to the upper foot pattern, keeping it in shape.
If one day I make a pair of socks out of famous slip stitch sole patterns, this would be one of them :-)

I’m very pleased with these socks, the pattern knits up well and looks great. Now I’m waiting for better weather to take some pics …

P.S I was right: I used 44 grams of the Regia black (whose original weight was 47 gr, not 50, as the ballband said), and 8 grams of the Merino black.
