After dyeing all that lovely fiber, you need to spin it up into some lovely yarn. You will find that if you put it in the carder, you are going to end up with a homogenized color -- so not what you were after. Below is an example of fiber that I spun into yarn. You see all the lovely colors?
To keep my colors separate, I carefully pull the locks open, keeping the colors in bands. Next is some of the wool pictured above pulled out into roving so as to preserve the different colored areas. Then I just spun it up thick and thin. I love just to let the fiber spin the way it wants to.
Below is the yarn I spun from this fiber. I Navajo-plied this yarn to keep the color bands together giving me a yarn that changes colors as it goes along it's length.
Below is another yarn that I spun the same way, only this time, I plied it with a thin yarn I spun out of angora rabbit fiber. You can also use embroidery thread or even a commercial fiber to ply with. Let your imagination run wild. At any rate, this method keeps those lovely bands of color that you worked so hard on in your crock pot dyeing project.
