This pattern uses the spiralling stripes technique. If you've not used this technique before don't worry! It's fully explained in the pattern. The socks are knit from the cuff down and feature an afterthought heel.
The pattern uses a total of approx 400 yds of yarn, but you will need two colours, half of each.
The sample was knit in Knit Picks Chroma, shades Lollipop and Bare. Sadly Lollipop has been discontinued, but you can substitute the following to get the same effect:
For the cream yarn:
Alternatively, Lion Brand Sock Ease in colour Marshmallow, which comes in 100g balls.
For the rainbow yarn, try one of the following - you want a long colour change:
Katia Darling in 201 or 213 - this comes in 50g balls and you'll only need 1.
