This is a ballet flat style sock. The length is easily adjustable to foot size.
For an average size foot you can easily get a pair out of a 50g ball of sock yarn, possibly even 2 pairs.

I designed these for a pair of shoes I had trouble finding socks for, all the ‘no show’ socks always stuck out and looked ugly. They also make for a nice light summer slipper in the house.

Enjoy!
