Blue dye has existed in the world for more than 6000 years. In China, as early as the Warring States Period, Gou Zi, a representative figure of Confucianism, knew that more beautiful green colors could be dyed from the green bluegrass, so he left behind a sentence that "green is better than blue".
The natural instability of blue dye due to different factors such as dye fermentation and oxidation contributes to the unique charm of blue dye. You can't imagine how your own works will be presented to you in a unique form.
At present, the most common skills in blue dyeing are tie dyeing, batik dyeing and maple printing
