A simple blended strip pattern that with some simple maths is easy to adjust to multiple sizes.

I used a MC and then 4 contrast colours but it is up to you, let your imagination run wild.

This would be great for scrappy socks as each stripe is only 5g per sock. So if you want them matching your would need 10g for a pair for each stripe (plus extra for heel and toe in your colour, normally around 10g)
