I’ve just put the beans to dial in cool water in a large jar. I’ve used 100g beans so will see what weight of yarn I can dye with these. Now I have to wait for 24 hours, shaking it gently now and then.

It’s 24 hours later, and time to get the due working. Of course I’d overlooked the problem of getting the liquid or without disturbing the beans. Instructions said to stop shaking the beans at least an hour before adding the fibre, so I did that. Then to remove the liquid carefully as any bean debris will turn the dye brown. However, it’s not easy to get the liquid out without the beans when you’ve stupidly put it in a narrow-ish mouthed jar!
Luckily I found a small ladle in the kitchen that just fitted, so managed to get some out. Not sure if it’s enough. I’ve added plenty of salt and enough water to cover the yarn and am now waiting…

It did not work sadly. But I may try again with more means this time.
