[Storage box] Wooden box made especially to store obi which is rolled on a card tube wrapped in paper and then wrapped in tissue and yellow cotton
[Length] Length of woven cotton obi fabric, densely striped in shades of black and grey. Approximately 2120 warp threads (60 threads per cm), with 24 wefts per cm. The dyes were created using natural plant extracts: the black is created from indigo with peels of pomegranate, the grey with the branches and leaves of the ring-cupped oak, Japanese chestnut and fragrant olive. There are 6-10 gradations within the colours.
Noriko Tsuiki has revived the techniques of kokura-ori from her native Fukuoka in south-west Japan. Using cotton threads she dyes herself, Tsuiki weaves densely striped fabrics which reveal a supreme sensitivity to colour. This length of fabric is entitled 'Thunder of Cascade' and is inspired by the sounds and the atmosphere of a waterfall. 2120 warp (vertical) threads have been used (60 threads per centimetre), three times as many as in normal plain weave cotton. Natural plant extracts of indigo, pomegranate, and the leaves of oak, Japanese chestnut and fragrant olive, have been used to create the many shades of black and grey.
