For the next one, I'm going to do the peasant heel on 60% of stitches instead of 50%. I'll be writing it up as a basic pattern for self-striping yarn. I'll even throw in multiple sizes! :)
Also, I'm trying to work out the logistics of how I would teach a class on dyeing self-striping sock yarn. The methods I use at home would have to be adapted for space and available equipment.
