I had a small roving of white wool, and I decided that I would hand paint it. I used food coloring for the dies, and it turned out to be a pastel rainbow. I wanted to spin it so that it kept it's graduation of color, so I spun it from end to end, rather then pulling batts off the roving. Then, in stead of two plying it I navajo plied it, so it continued that graduate of color. Then I wound it on the ball winder, again, still keeping the color changes. And now I am knitting it in to a head band (for there is not enough to do much else with it), continuing the graduating colors. (I will post photos of the finished head band later).
