Craftspeople interested in traditional methods will welcome this complete guide to making and using dyes from plants. Although its emphasis is on plants of Northeastern North America, many of the plants listed are found throughout the world.
Helpful introductory chapters on equipment, mordants, dyeing procedures and other essentials, are followed by individual plants: its suitability for dyeing, useful parts, how to process them, colors, dye fastness, plant identification, where to find it, and more. Also include four valuable indexes — plants by common name, botanical name, by colors produced, and a general index. A list of suppliers, metric conversion tables and other information rounds out this thorough guide to safe, ecologically sound dyeing methods.

surprisingly readable for what amounts to a text book. The instructions are clear and understandable to the novice. ( )

A good reference book. ( )

A well-organised guide that will allow you to raid your garden, nearby park, or highwayside for leaves, bark, roots, and flowers capable of producing dye! It takes you through all the steps (listed in Amazon's description) clearly and well.
Some of the chemical mordants suggested may not be available in local stores, but I'm sure a quick net search would turn them up. Alternatively, the book lists several household chemicals and methods for producing fast dyes, some of which could be safely used by older children. ( )
