This pattern is in english, with charts.

The openwork looks like little butterflies or bow ties.
The cuff is completely worked in this pattern.
Leg and foot are decorated with openwork only at the front,
at the back there are two ribs.
The socks are knitted top down, with a French Heel and a Flat Toe. But of course you can knit another heel and/or toe.
