This pattern enables you to use any 4-ply (fingering) yarn. I estimate that you should need somewhere between 15 - 20 grams of yarn to complete two socks. You can alter the pattern by adding or decreasing rows before or after turning the heel to make longer or shorter socks.

I have found this recipe is terrific for using up the yarn leftover from knitting adult socks. This pattern would also be useful for teaching beginner sock knitting.
