Oh well, not everything turns out as we would like. These are the results of my dyeing experiment with horsetail and I don't think I'll be hurrying back to pick more. The fleece was mordanted with alum and then dyed - the one on the right was then put into an afterbath of copper to see if I could get it to turn green.
Not the best colour representation, but the one on the left turned out a sort of pale creamy yellow, very nondescript, and the other one is a sort of sludgy colour with bits of brown.
BUT, the good new is, the cotton seeds I planted last week from one of the bolls I pulled apart, have germinated :-
Three are through, and the fourth is on it's way. Just need the greenhouse to be finished for the autumn so I can keep them warm.
