If you're working with natural dyes, one of the most important (and often overlooked) steps is preparing your fabric properly. Today, I’m sharing how I make a soy mordant — a plant-based, non-toxic alternative to synthetic mordants — and why it's my go-to for creating vivid, lasting results.

What Is a Mordant?
A mordant helps natural dyes adhere to fabric. While many traditional mordants involve metal salts, soy milk offers a gentler, eco-conscious option that enhances plant pigment absorption, especially on cellulose fibers like cotton or linen.

Why Soy Milk?

• Sustainable and safe

• Ideal for delicate prints

• Enhances richness and durability of color

• Accessible and easy to use

How to Make a Soy Mordant:

1. Soak organic soybeans overnight.

2. Blend with water until smooth.

3. Strain through cheesecloth or a fine mesh bag.

4. Dilute with water to create your soy milk mordant.

5. Soak scoured fabric for 30–60 minutes, then hang to dry. Repeat once more for best results.

I’ve shared a music-only video on YouTube showing the process in action — a calm, meditative look into my preparation ritual.
