I knitted these socks as faithfully as possible, referencing the sock knitting method devised by Mr. Inotani. They are 100% wool socks. These socks feature a black and purple gradient. Black Purple Medium-fine yarn, 100% wool Angora wool (image 10) is added to the toes. Toe: Medium-fine yarn (3 strands) + Angora extra-fine yarn (1 strand), held together (4 strands total) Body: Medium-fine yarn (3 strands) Heel: Medium-fine yarn (4 strands total, with 1 extra strand added) Thick and slightly large. Foot size: 23.5cm Ankle length: 19.5cm As they are knitted, they are stretchy. I knitted them carefully with good quality yarn, but this is a hobby project. They are not perfect.
