In my new book I am focusing to some extent on native plants and fibres, so wool plays an important part – and not only white wool but also naturally-coloured wool. Recently I have been spinning naturally-coloured light brown and grey wool fleece and I love the effects when these skeins are dyed. The colours can be very subtle. Here are some examples:
From left to right: Madder, Indigo, Rhubarb Root
The first skein in each pair shows the dye colour on white wool and the second skein shows the dye colour on light grey wool.
All the skeins are unmordanted.
The samples above are from horsetail (left) and tansy (right) and show from left to right: alum mordant on white wool, no mordant + alkaline modifier on brown wool , no mordant + alkaline modifier on grey wool
I find alkaline modifiers extremely useful, especially when used on fibres that have not been mordanted with alum. Even when the colour on the dyed fibres looks rather insipid initially, an alkaline modifier can often deepen and brighten it. The results of alkaline modifiers on naturally-pigmented wool are particularly pleasing, as I think the samples above show.
