She then began work with natural dyes too and became intrigued by the individual trade histories of dyestuffs. Her extensive research into the nineteenth century orchil trade (orchil is a natural dye obtained from lichens) began in 2008 when an industrial archive came to light in her small Devon town. Her knowledge of making and working with orchil has brought her into contact with many international researchers working in conservation and science, and she has published several papers on her research work.
