Many of the dyes are made from lichens, the useful ones for this purpose being known as crottle.. The process employed is to wash the thread thoroughly in urine long kept ("fual"), rinse and wash in pure water, then put into the boiling pot of dye which is kept boiling hot on the fire.
Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources—roots, berries, bark, leaves, and wood—and other biological sources such as fungi. [1] Archaeologists have found evidence of textile dyeing dating back to the Neolithic period.
Mabel Burnside Myers, Vegetal Dye Chart, c.1970. Burnside Myers used vegetable dye materials in her work, [5] and is considered the first Indigenous weaver to invent dye charts from plant matter as guides to teach others about sources of dyes for use in weaving. Later, her dye charts were produced to sell on the tourist market.

A dye is a colored substance that chemically bonds to the material to which it is being applied. This distinguishes dyes from pigments which do not chemically bind to the material they color. Dye is generally applied in an aqueous solution and may require a mordant to improve the fastness of the dye on the fiber. [2]
