KATAZOME with Indigo Dyeing

AYA Fiber Studio 

Jan. 25-27, 2019


<Additional Information>

We will use traditional Japanese tools (*Harite & Shinshi) for the Katazome with Indigo Dyeing workshop.

We will hang to dry rice pasted fabric after pasting together using Harite & Shinshi.  Then you will dip your piece individually in to the indigo dye vat.


I will lend 3 sets of Harite and bunch of Shinshi sticks.  I will ship them from my studio to Aya Fiber Studio and everybody can share them during the workshop.

*Harite: a pair of clamps set with small nails. They are attached to the ends of the fabric and tied with rope. 

Shinshi: bamboo stretchers. These are resilient bamboo rods with needle points set in each end.  Keeps fabric stretched with even tension for dyeing and painting. 


We will finish approx. five to six pieces (approx. 19”x 14” each) during the workshop.  NOTE: Try to make various designs with small pieces.  Applying a larger/longer piece of fabric is difficult to do in the classroom situation. You will be able to produce large/long pieces at home later.

PRE-WASH for cotton, linen, bamboo, rayon: Get enough warm water to cover cotton or linen fabric in a pot.  Wash well with mild soap in hot water.
