PLANT → VAT → DIP → GREEN → AIR → BLUE
Immersion in indigo: a day at a living vat. The ancient art of natural dyeing — from the first stir to the last knot undone.

You step into a craft more than six thousand years old: learn to work with a living dye vat and draw out shades of your own, from pale sky blue to deep navy.
Vladimir, who studied the dyeing traditions of India, Sri Lanka and Vietnam, introduces the philosophy and symbolism of indigo, and shows how to prepare the cloth and how to build and keep a natural vat.
This is more than a dyeing technique: a slow practice that joins craft, culture and nature — an alternative to toxic synthetic dyes. You learn how pigment and fibre bond, what natural indigo does for the skin, and how the process can become part of a more attentive way of living.
Programme · 6 modules
Philosophy and history
The philosophy and history of Indigofera tinctoria, from ancient Egypt to Japan.
Preparing the cloth
Getting the fabric ready: knots, folds, soaking the fibre.
Building the vat
Making and tending a natural indigo vat — the living creature of the workshop.
Dyeing
Dip after dip; each one opens a new shade.
The birth of shades
From sky blue to deep navy — a play of light and time.
How it works
The chemistry of plant indigo and how it bonds with fibre.
01 — Preparing the vat
A first meeting with a living thing — our indigo vat, the heart of the workshop. It holds a whole small world that has to be fed and respected. Carefully, without upsetting the balance, we lower the stick and begin to stir. Inside the vat, the colour itself is breathing.
02 — The philosophy of indigo
In ancient Egypt as in Japan, this deep, secretive blue stood for the sky, for boundless wisdom, for the passage between worlds. The philosophy of indigo is woven into the dyeing itself: a lesson in patience, in waiting, in trusting the process.
03 — Making the pattern
The dye is ready and the vat is breathing — time to prepare the cloth. Everyone makes a pattern of their own. Every tight knot and every deep fold lays down the pattern to come. There is no right or wrong way here.
04 — Soaking
Once the patterns are held fast with thread and cord, the cloth goes in to soak. The fibres must be wet through, so that when they meet the alkaline indigo bath the dye goes in evenly and deep.
05 — The main alchemy
Guided by Vladimir, everyone lowers their prepared cloth into the vat and learns how to hold it there. The first dip lasts only a few minutes. We lift the cloth out carefully — and it comes out of the vat not blue, but green.
06 — Alchemy complete
After dyeing, the cloth is rinsed in clean water to wash away the dye that has not taken. The last step before unfolding: clearing the cloth of everything extra, so its real beauty can come through.
07 — Fixing
To keep the colour fast, the cloth goes into a bath that fixes the pigment. It is like grounding — a soft, necessary ending after an intense meeting with living colour.
08 — Unwinding
With every knot undone your own pattern appears — a print of the vat’s movement and breath. A moment of delight and of seeing the whole process.
You have not just dyed a cloth — you have made a living piece of work.
