Natural Dyes (Textiles Handbooks) by Linda Rudkin, published by A & C Black Publishers Ltd (August 20, 2007), distributed in Australia through Allen and Unwin.
This in an interesting technical guide to natural dyeing. Lots of information in one place – with extensive info on mordants and dyestuffs as well as some information on the process, materials and health and safety. The bonus is that the second half of the book has sample boards of the different dyestuffs used on various materials and used with different mordants.
My only complaint (well two really) I am not exactly sure about the accuracy of the colours, some pages seem to dark or dull or else overly bright – and as this is a book giving examples of what various plant dyes look like this is a bit of a downer. Another annoying thing – is what appears to be a design fault with a printing error at the top of every page.
