I handspun the yarn, which is a merino and silk blend. Then made a 3ply yarn from it .... and had to spin up some more when I didn't quite have enough to finish the job!
And I then hand crochet the socks. They are from an Annies Attic pattern that I had to adjust slightly as I made these for my husband and the pattern is not really "man size". It took a few goes with different size hooks to get the size right. The yarn I made is 12wip and the hook size I eventually settled on was 5mm.
