Indigo dyeing begins with sowing seeds in a field.

That beautiful indigo color is created from the soil of the field. It starts with seeds and ends with seeds. Indigo dyeing has been continued as part of a farming lifestyle.
It is a mystical and truly不思議な dyeing process, so if you are interested in indigo dyeing, want to try dyeing, or are interested in dyeing from the field, please join us.
Also, for those who want to grow indigo themselves, we will distribute seeds. Please try growing indigo even a little, in a field or at the corner of your garden. We would be happy if you could continue to connect the seeds.
This project uses a 130-liter pail (large bucket) for dyeing, so it's a size that allows you to set up and manage your own indigo vat even if you don't have a dedicated one.
Please try to attend all sessions. If you are unable to attend for unavoidable reasons, please let us know.
Capacity: 10 people
Participation fee: 42,000 yen (participation fee for all 6 sessions)
