Katazome is stencil paste resist. Technique overview: design and cut a stencil from a strong flexible paper. Then you add a net to the paper to reinforce it. Next, mix up some paste and apply it through the stencil. Wait for everything to dry, then dip your fabric in indigo multiple times. Finally, wash out the fabric and the paste and see what you have.
Here’s my first try at cutting a stencil and dyeing over it with indigo.
