Small knit series -Socks on holiday

I like to take a new project with me on holiday. My New Zealand trip was very enjoyable, with some terrific stops at knitting shops and trials of new-to-me-yarns -( loot to be revealed later), and I also finished a pair of socks within a week, whilst knitting on the plane and in the car.



This sounds rather productive until I reveal that they were socks for a 9 year old boy.
He even agreed to model the socks on location.
The yarn is Heirloom Jigsaw Self Patterning Sock Yarn, colourway 81, and the pattern is our StitchBliss child's sock pattern.
I probably have enough yarn left from the 100g ball for another pair,but am feeling like a more varied colour palette- maybe some fair isle?
