This is a commercial white tweedy bit that was an awfully, stark shade of white. I've not yet found a project that particular shade of white worked with, so each time, I dyed it. I'd bought 10 or 15 balls on super sale. The last two balls were turned into large skeins, tied with 4 ties and ceremonially dumped into a pot of grey weak acid dye. I used a 1% dye stock with vinegar as my acid. It's still wet here, but it turned out perfectly.
This is fibre reactive dyes on superwash Merino. The brightness of the colours always bring me joy. I learned to dye wool with fibre reactive dyes, using a 2% stock solution. The last time I mixed up dyes, I'd just done new acid dyes at 1% and did the same with the fibre reactive dyes. However, what I found was gorgeous colours on wool, that exhausted, rather than leaving excess dye to wash out. I'll need to explore this more.
Pumpkin coloured acid dyes on superwash Merino mill ends. In the pot, this was gorgeous. However, despite getting it to temperature for more than enough time, when I rinsed it, yellow dye kept running off. I put it back in the pot, with more vinegar, brought it up to temperature, kept it there for an hour again. Despite the dye pot water exhausting, it still ran yellow when rinsed. I tried one more time, dumping in a whole whack load of vinegar. I heated it for almost 2 hours. So far it seems okay, but it's lost those lovely variations in colour and the oranges of sort of melded into one shade.
Speaking of orange - gratuitous photo of a lounging Phil. He can be very vocal and pushy when he wants to be petted. He has a much nicer coat, after a year of decent food. When he adopted us and we let him in the house, he had almost no undercoat. I don't think he would have survived the winter outside. He would sleep under the covers on the very cold evenings. He still does like a cuddle on cooler days.
This is on my Minstrel right now. It's jelly bean or ju jube coloured merino/cashmere blend. It's spinning beautifully. I'm trying to decide if I want to ply it with itself, or spin up some navy blue for plying...
