Well, frustratingly, I haven't managed to try out my new spinning wheel yet and probably won't get an opportunity to do so now until next week.I have done a bit more dyeing, though.
I've got rather a lot of yellow yarns in the stash at the moment and decided to have a go at overdyeing some of them with logwood in the hope of getting greenish colours.
The first dyebath was made up with just 10g of logwood. Into this went 100g of wool which had been dyed in October with some apple mint from the garden and had turned out a very much paler yellow than the one I got back in August from the same plant.
I guess I left the yarn in the dyebath too long because it turned out a dark bluey purple. I must admit I was rather surprised to get such a marked colour change with only 10g of logwood. So, no green there then. That yarn can go and join the ever increasing pile of dark purple yarns I've got - it's a good job I like purple.
The second dyebath consisted of 44g fustic chips with 6g of fresh logwood chips, the 10g used logwood chips from the first dyebath and, just for good measure, an extra 6g of turmeric to increase the depth of yellow. (Now I keep detailed notes, of course, I have all this information at my fingertips.)
The first yarn in the dyebath was an undyed yarn which had been mordanted with copper and vinegar. This turned out a blue with only just a hint of green - nice colour, though.
The second yarn in the dyebath was a yarn which had been mordanted with copper and vinegar then dyed with turmeric. The original colour was quite a deep mustard yellow. At last, this one turned out green - an olive green. Just what I want for the next knitting project.
