How To Use Yamato Indigo Dye Garment Kit

50g of Yamato Indigo Dye
100ml of 30% vinegar
100ml of Fixative
30g of Sodium Hydrosulfite
30g of Soda Ash
A pair of latex gloves

2 to 3 Buckets
A stick to mix the dye
Scrap paper
White vinegar
Latex gloves


1. Put on the rubber gloves. Mix 50 gram of Yamato Indigo with 10 to 17 liters of water in a bucket (or 3 to 5g of dye per litre of water). Stir well for 1 to 2 minutes. The indigo vat will be ready to use instantly.

2. Skim off any bubbles from the surface of the vat with scrap paper.

3. Rinse the fabric or clothing item you wish to dye in water, squeeze well, then dip it in the indigo vat for 5 to 10 minutes. Make sure to submerge the entire fabric in the vat. Massage the fabric in the vat for a darker, more even result.

4. Take the fabric out of the indigo vat, squeeze out the dye liquid well, and expose to the air for 5 to 10 minutes in order for the dye to oxidize. The fabric may appear green at first, but will turn blue as it oxidizes. Make sure the entire surface of the fabric is exposed to the air in order for it to fully oxidize.

5. Repeat steps 3 and 4 if you wish to dye your fabric an even darker blue color.

6. After the indigo liquid is weakened, add a bag (30g) of caustic soda (soda ash) and sodium hydrosulfite and stir well to make the vat dyeable again.

7. After finish dyeing, rinse the fabric well in water until the water runs clear.

8. Mix a bottle (100ml) of 30% vinegar with 5 liters of water. Soak the dyed fabric into the vinegar water for 5 to 10 minutes and rinse in water.

9. Mix a bottle (100ml) of Fixative with 5 to 10 litres of water. Soak the fabric into the fixative, and massage the items so that they are well-submerged in the agent, and leave to soak for 5 to 10 minutes. Remove the fabric from the bucket, wring out any excess liquid, and leave to air dry without rinsing the fixative from the fabric.


When dyeing brand new fabric, make sure to wash it beforehand in hot water for even better results.

Be sure to add the vinegar water to the exhausted dye vat before draining.

The fixative will enhance and preserve the Yamato Indigo color onto your dyed fabric or clothing items, and will prevent the color from fading. The fabric cannot be re-dyed after being soaked in the fixative. The indigo vat may be kept for up to one week if it is sealed well and not exposed to the air.

Please keep your Yamato Indigo powder dye dry and use within a year of purchase for best results.


Please make sure to wear latex or rubber gloves and clothes that you do not mind getting stained, and use the dye in a ventilated place.
