Natural Dyes by Judy Hardman and Sally Pinhey

Natural Dyes is the best handbook for recipies for dying fabrics with plant material.  It describes the use of plants that can be grown or collected for dying fabrics.  It is lavishly illustrated with botanical watercolours and samples of the dyecolours achieved from each plant.   Judy's recipes are carefully researched so that a precise quantity of plant matter can be matched with an exact quantity of material.   This ensures the best  colour result and there is no residue to dispose of.
