In the recent and the ancient past, dyes from many different plants were used to color cotton, linen, and other fabrics. Since the middle of the 19th century, however, natural dyes have been almost completely replaced in industry by synthetic dyes, and today, the use of natural dyes is largely confined to individual hobbyists.
Any reader interested in experimenting with natural dyes is encouraged to choose not only those plant materials included in Table A3.7, but to try any local plants available. The experimenter will soon find that quite unexpected colors may be derived from plants, as the colors of fresh flowers, bark, or leaves often bear little relationship to the colors of the dyes. For methods of dyeing, see the footnote given under the heading of "Lichens" in Chapter 19 and references in the "Additional Reading" at the end of Appendix 3.
