The cone, a vivid red on the orangey side, became this (first photo) yesterday and then this (second and third photos) today.
My problem was in not owning a dyepot big enough, if one exists, to allow 650 g of dk cashmere to float around in freely to let all the dye sift equally through everything; those three hanks I’d wound up barely all fit in there with the water at half full. And it was a big pot. (Side note: surely there are people who can hold up an increasingly heavy niddy noddy long enough to wind two thousand-plus yards onto it to make a single hank out of that much yarn; I am not one of them. I had to take breaks.)
Honestly, still pretty bright.
No problem. Easier to add than subtract. I repeated the process today, putting in first that which had taken up the least.
Not perfect but a lot better and a lot more even.
My daughter is knitting. And I had a chance to give her cashmere. All it needed was some prep work.
