Here's the result of my first attempt! It went rather well. I used vinegar and Wilton cake coloring, worked like a charm. So, much easier than I ever expected. Will post some follow up pictures of the finished hat that I am knitting as a tester with this yarn. So far I think it will be a beauty.
My first attempts are purely tests. My next step is to figure out how to formulate consistent color ways and dyes to make more runs, rather than just one or two skeins of completely unique yarn.
I'm pretty sure I may have found my calling.
