I've been collecting material from the garden and local lanes to produce a series of natural dyes and stains using ancient techniques and hand-me-down recipes. I've researched the chemical reactions that affect the way the colours are produced and behave using iron and copper mordants, soya milk, leaves, flower heads, roots and bark.
