Material:
Fabrics (natural fiber for dying)
Latex gloves (to keep your hand from getting wet/dye)
Binding materials (Rubberbands, cotton strings, wooden pieces, pingpong balls, corks, etc)
Clamps or clothes pins
1 bucket of water (for presoak)
1 bucket of water (for dye)
Indigo Dye kit (Pre reduced Indigo Dye & Reducing agent )
A wooden stir stick.
Drying Rack (that will be okay if it is stained)
Vinegar
Water
Preperation for the Dye Vat:
a) Add dye and reducing agent.
b) Use the stirring stick and stir clockwise vigorously forming a vortex in the center of the bucket until a mass of bubbles forms there. (maybe 5 min)
c) When you see a mass of bubbles, slowly drag the stick the opposite way along the edge of the bucket making sure not to disturb the bubbles (bloom) at the center
e) Leave the mixture for an hour or overnight.
f) Once the vat is set, remove the bloom in the center with a strainer and it is ready.
Process:
1 - Choose a technique (Kumo, Itajime, Nui), and do it to the fabric you intend to dye.
2 - Soak the materials in the bucket of water for a few minutes. Wring out excess water.
3 - Dip fabric into indigo dye vat and leave it for 3 - 5 minutes (depending on fabric thickness)
4 - Slowly take material out and squeeze the dye back into the bucket.
5 - Put on drying rack and it will look green but will gradually turn blue as it is exposed to oxygen.
6 - Once the fabric is blue, repeat the process (3 -5 times. The more times, the deeper the blue)
7 - When happy with color, Rinse the fabric in water (use the presoak vat again and rinse until the water is clear.
8 - Let the material dry completely.
9 - Set colors by soaking in a mixture of 80% vinegar and 20 % water (overnight)
10 - Wash with blue jeans / dark clothes in a washing machine for final wash. Done!
