I tried to dye up a sweater's worth of yarn today. My goal was to have a yarn that was semi solid in a light olive green. What I got was this:
My pot was WAY too small for the amount of yarn. By the time I jammed all the yarn in, the yarn to hit the pot first has essentially sucked up all the dye in the water. I knew enough to hold the yarn so that each skein entered at the same time, so each skein is similar, but I've got one end that is a darkish browny olive and the other end a very pale green. Live and learn.
Maybe I can salvage this and make it usable by over dyeing. In any case, I don't think I will be using this for the project I intended. C'est la vie.
