Dyeing fabric with herbs involves simmering plant material in water to extract color, then using that liquid to infuse the fabric. Here’s a step-by-step guide:
Steps to Dye Fabric with Herbs
-
Prepare Your Fabric:
- Use natural fibers like cotton, linen, silk, or wool. Synthetic fibers don't absorb natural dyes well.
- Scour the fabric to remove any sizing, oils, or finishes. This helps the dye adhere evenly. Wash the fabric with hot water and a pH-neutral detergent.
- Mordant the fabric. A mordant is a substance that helps the dye bind to the fabric. Common mordants include alum (potassium aluminum sulfate), iron, and tannin. The type of mordant you use can also affect the final color. Follow mordanting instructions specific to your chosen mordant and fabric type.
-
Gather Your Herbs:
- Choose herbs known for their dyeing properties. Good choices include:
- Onion skins: Yield yellows and oranges.
- Marigolds: Produce yellows and golds.
- Chamomile: Creates soft yellows.
- Blackberries: Offer purples and pinks.
- Madder root: Gives reds and oranges.
- Walnut hulls: Result in browns.
- Use fresh or dried herbs. Dried herbs often have a more concentrated color.
- Choose herbs known for their dyeing properties. Good choices include:

Create the Dye Bath:
- In a stainless steel or enamel pot (not aluminum, as it can react with the dye), combine the herbs and water. A general guideline is to use twice as much water as herbs (by weight or volume). You may need more depending on the herb and desired color intensity.
- Bring the mixture to a boil, then reduce the heat to a simmer.
- Simmer for 1-2 hours, or until the water is a rich, concentrated color. Stir occasionally.
- Let the dye bath cool slightly.
-
Strain the Dye:
- Carefully strain the herbs from the dye bath using a fine-mesh sieve, cheesecloth, or muslin bag. This removes any plant material that could leave spots on the fabric.
-
Dye the Fabric:
- Submerge the mordanted, dampened fabric in the dye bath. Ensure the fabric is completely covered and can move freely.
- Gently heat the dye bath to a simmer, then maintain a low simmer for 1-2 hours, stirring occasionally to ensure even dyeing. The longer the fabric stays in the dye bath, the deeper the color will be.
- Turn off the heat and let the fabric cool in the dye bath overnight. This allows for maximum color absorption.
-
Rinse and Wash:
- Remove the fabric from the dye bath and rinse it thoroughly under cool, running water until the water runs clear.
- Wash the fabric gently with a pH-neutral detergent.
- Dry the fabric away from direct sunlight to prevent fading.
Important Considerations:
- Color Variations: Natural dyes can produce unpredictable results. The final color can vary depending on the type of herb, the mordant used, the water quality, and the dyeing time.
- Lightfastness and Washfastness: Natural dyes may not be as lightfast or washfast as synthetic dyes. This means they may fade over time with exposure to light or repeated washing. To improve lightfastness and washfastness, consider using a post-mordant or after-bath treatment with vinegar or salt.
- Safety: Always wear gloves when working with mordants and dyes. Work in a well-ventilated area. Keep dyes away from children and pets.
- Record Keeping: Keep detailed notes of your process, including the type and amount of herbs used, the mordant used, the dyeing time, and any other relevant information. This will help you reproduce successful results in the future.
