Self-striping is a labour of love, and many dyers have a love/hate relationship with it. They love the way it turns out, but hate the process. Many of us will make a colour way then declare it is too much work and that we are never going to to do it again, and then find ourselves planning out the next one as soon as we start knitting with the last one we did.
I have three methods that I have used for this, and I will admit that at least one of them in not perfect. But before I get into the method, there is one thing I want to stress - self striping is not an exact science, so cut yourself some slack. The dye may bleed into the section next to it, changing the length of your stripe. Or you may think you have measured correctly, just to find out once section is shorter or longer than the rest. It's all good. No one (except maybe you) is ever going to examine the yarn or the finished item and declare that it is imperfect because one stripe is off by a couple inches. If there is someone in your life that would do that, don't show them your yarn. you don't need that kind of negativity when doing something that is so much fun.
