100 % Natural Indigo | Origin: India | No synthetic additives

Harvested and processed in southern India, this true indigo powder delivers the deep, cool blues prized by dyers for centuries. Because indigo is an insoluble pigment (not a dye that bonds with a mordant), no mordant is required—just a reduced (oxygen-free) vat.

Why choose our indigo?

• Authentic & plant-based – Derived solely from Indigofera tinctoria leaves; never synthetic.
• Economical – ≈ 50 g colours 3–4 kg of wool to a strong mid-blue.
• Low-energy process – Vats work at 30 – 40 °C; no hard boiling.
• Versatile methods – Suitable for any indigo vat, be it fructose, mineral or bran-ferment vats, yeast vats, sig vats or quick hydros vats.
• Excellent colour-fastness – Outstanding on deeper shades, good on lighter blues.

Typical yield
• Pale sky blue – 1 g per 100 g fibre
• Medium denim – 5 g per 100 g fibre
• Deep navy – 12 g + per 100 g fibre (multiple dips)

Quick-start options
• Organic Sugar Vat – Indigo + lime + fructose (no fermentation wait).
• Yeast Fermentation Vat – Gentle, long-lasting; see recipe below.
• Hydros Vat – Fast one-hour reduction (includes chemical oxygen remover).

Yeast Vat Recipe (500 g fibre)
9 l water · 110 g sugar · 50 g preservative-free dried yeast
30 g bicarbonate of soda · 40 g indigo (ground)
• Maintain 40 °C (not above 50 °C).
• Reduce for 48 h until liquid turns yellow-green with a copper sheen.
• Dip pre-wetted, unmordanted fibre; oxidise 60 min; repeat for depth.

Storage & safety
Store in a cool, dry place, sealed against moisture. Wear a mask when handling fine pigment and gloves when working with lime, hydros or iron additives. Dispose of spent vats responsibly.

Organic Ground, Cut, or Whole Hibiscus Flowers
Vibrant Pink & Purple Hues for Dyeing | Cultivated in Egypt

Hibiscus flowers are an excellent choice for natural dyeing, offering stunning shades from light purples to deep pinks and even greens, depending on the mordant used. Ground Hibiscus produces a lighter purple hue on wool, while cut or whole flowers yield more vibrant tones. This pH-sensitive dye is perfect for hobby dyers and children’s activities, as it offers interesting colour shifts - from green to purple to pink -  and an experimental approach to dyeing.

Dyeing Tips:

• Ground Hibiscus: Use 50% of the dye weight relative to the fabric for a light purple hue.
• Cut or Whole Hibiscus: Use 75-100% of the dye weight relative to the fabric for deeper tones.
• pH Sensitivity: Hibiscus dye is pH-sensitive, meaning colour can shift, creating fun and unique results—perfect for those who enjoy experimenting.

Colour Fastness: Poor (colour may shift with pH changes)

Basic Hibiscus Dye Recipe:

1. Mordanting: Use Alum (10-15%) for dyeing wool.
2. Dye Ratio:
   • For mordanted fabric or yarn: Use 50-100% Hibiscus dye relative to the weight of the dry fibre.
3. Dyeing Process:
   • Soak Hibiscus flowers or powder in water and simmer.
   • Add mordanted fabric and simmer until the desired colour is achieved.

A delightful and experimental natural dye, perfect for adding beautiful, ever-changing shades to your projects!

GLOSSY BUCKTHORN BARK DYE (Frangula alnus)
Dye Colour: Golden Yellow, Pinks, and Reds | Country of Collection: Bosnia

Glossy Buckthorn Bark is a pH-sensitive natural dye, wild-collected in Bosnia. Historically valued for its versatile colour range, it delivers golden yellow tones at a neutral pH, shifts to pink and red at higher pH levels (10–11), but it is unstable; and can yield green with the addition of iron. This bark’s gentle fragrance and good colour fastness make it a favourite among natural dyers and paint makers alike.

Colour Fastness: Good

Colour Outcomes by WOF Ratio

• 65g Buckthorn Bark per 100g Fibre
  Produces a spectrum from golden yellow at neutral pH to rosy reds at alkaline pH (unstable), with iron modifying towards green.

Basic Recipe for Dyeing

Ingredients: 65g Buckthorn Bark, 100g Mordanted Wool (approx. 13g Alum)

1. Soak bark for 2 days.
2. Simmer the bark in water for 2 hours; strain through cloth.
3. Add wool/fibre (along with the bark in a dye bag if desired) and simmer 1 hour.
4. Rinse well and allow to dry.

OAK BARK DYE (Quercus spp.)
Dye Colour: Golden Beige and Browns | Country of Collection: Poland

Oak Bark is a tannin-rich, natural dye source used for centuries to achieve warm, earthy tones on wool and silk. Thanks to its high tannin content, no mordant is strictly necessary, but will result in better colour fastness. Experimenting with iron and adding oak galls can deepen or modify your results. Lighter beige tones emerge with lower pH (around 5), and deeper browns develop under higher pH (around 8), though iron is a more stable solution for darker tones.

Colour Fastness: Good

Colour Outcomes by WOF Ratio

• 50–100% WOF Oak Bark
  Produces a range of golden beige to medium browns, with the flexibility to go darker by adjusting the pH or boosting tannins with oak galls.

Basic Recipe for Dyeing

Ingredients:

• 50–100% Oak Bark (by weight of fibre)
• Wool or Silk (mordant not strictly necessary due to high tannin content)

Instructions:

1. Soak the oak bark overnight in water.
2. Simmer the soaked bark for 2 hours, then strain through a cloth.
3. Add wool or silk to the dye bath.
4. Simmer gently for 1 hour.
5. Cool & Rest: Allow the fibre to soak in the dye bath overnight to deepen the colour.
6. Rinse & Dry: Rinse the dyed fibre in cool water and hang to dry.

Embrace the rich tradition of oak bark dye and bring timeless, organic hues to your fibre projects—perfect for both beginners and seasoned natural dyers.
