I've been putting off a dye day for a long time, both because it's lonely to do it by myself now that I've moved so far from my counterpart, and because my new house is not at all conducive to the dye process.
First, I have to mix the dyes from powder. Dyes are extra-toxic in powder form, so I do this in my basement. This involves hauling super-hot water down to the basement from the kitchen, since there's no sink/faucet in the basement, and then propping everything on top of the washing machine, because there's no table. Then, I have to clean the washine machine, because I inevitably splash dye about. I put my dye containers (which are 32oz and plastic) in a big box, and haul them upstairs, along with my squeeze bottles. I now have two boxes of containers, and more squeeze bottles than fit in the carrier I use (which I call a grooming box, 'cause that's what they're used for in the horse world, where I used to live).
I mix my colors over the sink, because it's too dark in the basement, and there's no drainage, so again, more mess, at least this part's in the sink. I have one small piece of counter on to which I can lay rovings to prep them for steam-dyeing, which isn't really enough space. Plus, I have to clear off the counter, since it's usually full of my cutting board, knives, and other kitchen ephemera.
After the yarn/roving is dyed, I haul it back down to the basement so that I can whirl it about in the washing machine on spin cycle to pull some water out. Then back upstairs, where I hang it in my bathtub to dry.
Oh, for a studio. I'd make so much more yarn in a studio. I guess I get more exercise this way, but it's awfully high-maintenance.
