I've been meaning to try this one for a while...another thing I have so much of in my garden. It's everywhere on walks too, and so pretty.
This was a slow process, which seems to be suited both to natural dyeing and to me, when I put things a pot to soak and then don't get a chance to get back to it for a couple of days. It really was intentional this time though.
The yarn became a lovely, buttery yellow. One thing that really struck me was the difference between the full skeins, and a tiny little sample one that I added to play with later. All dyed together, at the same time but much, much paler. The difference here was scouring - the full skeins were properly scoured and rinsed beforehand, while the sample well, wasn't. It made such a huge difference to how the yarn took the dye. Of course, I neglected to take photos and have since overdyed it - but the results are still striking and I'll show that next time!
