artisanal natural indigo fabric processThe artisanal production process of BLUEHANDED’s indigo dyes fabric mainly includes following steps:
- Making master template. Draw or print the required pattern on craft paper, cut out the part of the design that will not be indigo dyed with a knife or hole punch. Then brush the masterplate with wax or paint to dry. The function of protecting the template is to extend the life of the craft paper.
- Making paste. Use lime powder, soy flour and water according to a certain percentage to make the resist paste, that is.
- Applying paste. Put the template on the untreated or dyed cotton fabric, apply evenly the well-prepared resist paste over the template with a spatula, which adheres to the white fabric through the cutout holes and are then hung out to dry.
- Put the fabric with the resist paste applied into dyeing vat for 20 minutes and then take it out to hang for 30 minutes, to let it oxidize fully. During this process, the white fabric will turn from yellow to green, then to blue. To repeat the above action 5 -8 times, can achieve the required dark blue color. The roll of fabric is hung to dry in the sun, an important part of the indigo setting process.
- Remove the paste. Scrape the resist paste on the surface of the dyed fabric with a large knife, to exposure the white pattern that was covered the paste.
- Wash away the residual resist paste and excess colour.
During the fully manual dyeing process, areas of the white lime pattern would ‘crack’ due to the large area of resist paste, to form the unique charm of the manual Lan Yin Hua Bu－“ice crack”.
