This linen fabric is Linen Gauze No 110, which is dyed with natural pigment from safflower and natural water , by the artist working in Kyoto.
The pigment is made by the artist herself raising safflower. There is very time-consuming job process in order to make safflower pigment, that is to soak the flowers in the water for 1-2 days and squeezing patiently. That exhausting work deserves this beautiful 100% safflower red.
In Heian era in Japan (some 1200 years ago), This color was banned for the general people, and exclusive just for the aristocrats, who are also long for this color.
Nicely dyed soft and smoky red color is nice as shawl or the garments such as blouse, and so on.
