I have tried natural dyeing, mainly using one of Jenny Dean's books, but I mostly got disappointing results with anything other than yellow
and even then I couldn't get the lovely clear gold I wanted from Anthemis Tinctoria, which I grew specially. I particulary wanted to get the lovely soft green she shows from Comfrey, but all I ever got, after many battles with the mucilaginous properties of comfrey, was sludge colour
At the moment I want to get reproducible results, which is why I'm after an alternative supplier of acid dyes. In searching for suppliers of the Jacquard dyes (thank you Chris H), I found that George Weil (Fibrecrafts) do a similar product in the colours I am used to and reasonable quantities, so I think I will try those - unless anyone has had a problem with them? I love mixing dyes to create something new. I will try to post some pics of what I have done in the past. I am keen to start again, especially as I have lots of white handspun Shetland yarn crying out for some colour
