‱ Condensed tannins
‱ Flavonoids (including fisetin & dihydrofisetin)

Suggested Quantities (WOF – Weight of Fabric):

Cut or Ground Bark
‱ 30–50% WOF (soaked overnight or simmered 1 hour)

Extract (sold separately, see link below)
‱ 5–15% WOF (dissolves directly in water)

Uses:

‱ Natural Dyeing of Protein & Cellulose Fibres – beige
‱ Iron Modification – create grey, warm taupe or darker brown/beige shades

Madder Dye – Cut or Ground
Rich Natural Reds for Dyeing | Wild-Harvested in Eastern Europe

Madder (Rubia tinctorum) is a renowned natural dye that produces a stunning range of reds—from warm oranges and rich brick reds to deep blood reds and fiery crimson tones. The final shade depends on multiple factors, including soil conditions, root age, mineral content of the water, dyeing temperature, and fibre-to-dye ratio.

Dyeing Tips:

  • Mordanting: Avoid cream of tartar when mordanting cold. 
  • Soaking: Pre-soak fibres for at least 12h-24h before dyeing.
  • Dyeing Methods: Madder can be used in both hot and cold dye baths. Adding chalk can help achieve better reds.

Colour Fastness: Excellent – Madder is known for its durability and deep, lasting hues.

Discover the beauty of natural dyeing with madder and create your own unique reds!

Basic Madder Dye Recipe

(Adjust quantities as needed to achieve your desired shade. Water quality will influence colour result. Oranges instead of reds are often more likely)

Ingredients:

  • 100g dried madder roots (soaked overnight and blended if possible, or use ground)
  • 100g mordanted fiber (Alum-treated)
    • Use 50g of fibre for darker reds or 300g for lighter shades
  • 7–10 liters of water
  • 6g calcium carbonate (chalk) (optional, for enhanced reds)

Instructions:

  1. Soak the madder roots in the dye pot overnight.
  2. Gently heat to 65°C (149°F) and maintain for one hour for red tones.
    • Higher temperatures will shift the colour towards brown.
  3. Strain the dye bath through a cloth to remove root particles.
  4. Add the mordanted fibre and the dye bag (optional, might result in uneven colour) back into the pot.
  5. Maintain a temperature between 65–95°C (149–203°F) for one hour to develop the colour.

IMPORTANT: The higher the temperature, the darker and browner the final shade.

100% Natural Indigo (Indigofera tinctoria)

Traceable · Traditionally fermented · Origin: India · Approx. 35-42% indigotin

This is a high-quality, truly natural indigo, prepared in India from fresh leaves of Indigofera tinctoria using a traditional natural fermentation process. The indigo is supplied in powdered form and produces clear, stable blue shades ranging from very pale sky blues to deep, dark navies.

All batches are subject to analytical controls to verify their natural origin. This additional level of checking provides reassurance and traceability in a market where adulteration and partial synthesis have become increasingly common.

The main colouring component is indigotin, valued for its excellent lightfastness and wash fastness when dyed correctly.

Use in textile dyeing

Indigo is an insoluble pigment rather than a mordant dye. In order to dye fibre, it must first be reduced from its blue, oxidised state into a soluble yellow-green form. This reduced indigo penetrates the fibre and then re-oxidises on contact with air — the moment when the characteristic blue colour develops.

This indigo is suitable for a wide range of vat systems, including natural fermentation vats, fructose or sugar vats, lime-based mineral vats, bran vats, and quick vats using hydros or thiourea dioxide. Vats typically operate at 30–40 °C, making indigo dyeing a comparatively low-energy process.

It can also be combined with other natural dyes, such as yellows or reds, to create layered colours including greens, purples, and complex overdyes.

Typical usage guide

For pale sky blues, approximately 1 g of indigo per 100 g of fibre is sufficient.
Medium denim blues are usually achieved with around 5 g per 100 g of fibre.
Deep navy shades generally require 12 g or more per 100 g of fibre, built up through multiple dips.

Other uses

Beyond textile dyeing, this indigo can be used as a natural pigment for paint making, ink, decorative finishes, and woodwork. When used as a pigment, it should be well ground into the chosen binder or medium to ensure even colour development and to avoid visible particles.

The plant

Indigofera tinctoria is a small shrub traditionally cultivated for indigo production and is thought to have originated in India. The plant and its dye are mentioned in some of the earliest Sanskrit texts, and indigo was long known as “the queen of dyes” before the widespread adoption of synthetic indigo at the end of the nineteenth century. Other species of Indigofera have also been used historically as sources of natural indigo.

Storage and safety

Store in a cool, dry place, sealed against moisture. Avoid inhaling fine powder and wear a mask when handling. Gloves are recommended when working with lime, hydros, or iron additives.

WELD DYE (Reseda Luteola)
Dye Colour: Yellow and Green (when overdyeing) | Country of Collection: Typically Europe

Weld (Reseda Luteola) is a renowned plant-based colourant with a rich history, often used to create high-quality dyes in temperate regions. Paired with other traditional dye plants like Madder, Woad, and Dyer's Chamomile, it yields beautiful shades of yellow, which can then be overdyed with Woad to create the iconic Saxon and Lincoln greens. Legend has it that Lincoln Green was the signature hue of Robin Hood and his outlaws, achieved by overdyeing Weld yellow with Woad blue.

Colour Fastness: Excellent

Colour Outcomes by WOF Ratio:

  • 100% WOF Dye (Weld): Produces a rich, vibrant yellow.
  • Overdye with Woad: Creates stunning, lively greens.
  • Use of Soda Ash: Intensifies yellow tones and helps with colour extraction.

Basic Recipe for Dyeing:

  • Ingredients: 100% Weld, 7% Soda Ash, Wool (mordanted with Alum)
  • Instructions:
    1. Soak Weld in the dye pot with Soda Ash overnight.
    2. Bring to a simmer for 1 hour.
    3. Strain through cloth and set aside.
    4. Add mordanted wool to the dye pot and simmer gently for 1 hour.
    5. For a paler yellow: Use the same dye bath for a second batch of mordanted yarn.
    6. Reuse the dye bath: It can be used up to 2 times for additional dyeing.

Embrace the rich tradition of Weld dye and bring centuries-old colours to your fibre projects, from vibrant yellows to lush greens when combined with Woad.
