Two developed mould - and a not so nice odour -
but after a wash and a rinse in lukewarm water with a bit of detergent the skeins were ok.
The colour is subtly variegated, I think it would be nice for a scarf.
Of course the cotton towel didn't pick up as much dye as the wool/silk blend. No mordant added.
This experiment was fun, and apart from my impatience (I checked the jars every other day...)
I want to try again with some other plant!
