After the coffee is extracted, there are a lot of discarded coffee residues. We think there will be a good colour in it. So we extracted the dye and used it to conduct dyeing experiments, which achieved very good results.

China now grows a lot of coffee. We found that there was a lot of waste after coffee extraction, which contained good pigments, so we recycled them into dyes and dyed them into beautiful colour cards. These are some new attempts of “Ancient Water”.
