my father wanted handknitted socks from very thin yarn. I was not successful in machine-knitting, therefore I looked for a handknitting pattern for very thin yarn.
Circumference is 92 sts in the round.
I take the heel for too big though my father has a high instep.
Unfortunately thin machine washable yarn is only available in colors mostly old people wear.
The yarn is great; I used it at least 20 times on the machine before I decided to knit the socks by hand.
