We get some of these mushrooms growing in our garden every year, and I've often wondered if they'd give colour. I looked them up in one of my dye books "The Rainbow Beneath My Feet, A Mushroom Dyer's Field Guide" and couldn't decide exactly which they were. The ones most similar though are reported to give orange when the yarn is mordanted with tin. I haven't used tin for years, but thought I probably had some somewhere. Sure enough I found a tiny bit in a jar so used it to mordant the skein I'd picked out.
This is the yarn I chose to dye - it's the merino/silk I spun in Spinzilla. I have no idea of the weight of the mushrooms because I forgot to weigh them, but the yarn weighs 35g so I thought I was in with a chance of getting something.
There wasn't a lot of dye stuff, but I chopped them up anyway and heated them in some water to extract the colour.
The dye looked quite promising :-
And here's the finished yarn. It's subtle, very subtle. In real life it's very pale yellowish, probably a bit too pale for me. I think this one might be going into the dye pot again.
At least I now know not to pick those mushrooms and just leave them for the mice. They were obviously not the ones I thought they were!
