This is a basic pattern for adult size socks. The description includes a pattern for 2.5 mm needles AND 3 mm needles (in English and Dutch). The pattern is based on European sizes and measurements.

For 1 pair of socks up to size 45, 100 grams of 2.5 / 3 mm yarn is needed.

The pattern is described to be knitted with 4 needles. If it is desired to knit with a round knitting needle, this is possible. Only the heel cannot be knit with a round knitting needle and needs to be knit with the 4 sock knitting needles (20 cm).
