This sock is knitted top down with an afterthought heel. It’s knitted in 3 colours, but only 2 at a time.
The playful dots and colours may be combined differently on the two socks and this pattern is very suitable for left over yarns. To know if there is enough contrast, you can take a picture of the different skeins beside each other and make it black and white. This makes the contrast show better.

The pattern comes in 3 sizes: 64 (72) 80 sts.
