polygonum tinctorium

April 26, 2011

fermenting polygonum tinctorium/ dyer’s knotweed in Japan  


The leaves are piled in layers and sprinkled with water. The pile is turned and water added every 2-3 days for a considerable amount of time, depending on the size of the pile. As long as 2-3 months for large piles. Known, in Japanese as sukumo

When fermentation is complete the compost-like mass is formed into balls or cakes, aidama. 


cotton yarn, each row a different shade.


the dye workshop at Kawashima Textile School.  Dyeing is a serious business and done in a very scientific manner. Careful notes and samples are kept.

Calligraphy practise with rice paste resist.
