Eco-printing on cotton can be a bit more fiddly than eco-printing on wool or silk. Cellulose fibres don’t take up plant dyes as easily as protein fibres do. I have spent about 5 years experimenting with how to best prepare cotton and leaves for eco-printing, and am now able to fairly consistently get bright, clear leaf prints.
I am delighted to be releasing my ebook, Gum Leaf Alchemy, to share this method with others. The process I have developed works particularly well with eucalyptus leaves, but I have also been getting some good results from experiments with other types of leaves, from both native Australian and introduced plants.
