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!

POMEGRANATE PEELS ~ CUT & GROUND ORGANIC ~ can be used as Tannin and as yellow dye

The pomegranate is a fruit-bearing deciduous shrub in the family Lythraceae, subfamily Punicoideae, that grows between 5 and 10 m tall. The pomegranate originated in the region extending from Iran to northern India and has been cultivated since ancient times throughout the Mediterranean region.

 Colourfastness: good - excellent

Recipe:

For how to mordant your Cellulose fibres, please see my blog post 

 How to mordant linen and cotton fabrics successfully – AppleOak FibreWorks

If you are using protein fibres, a simple 10%Alum bath will do for mordanting, but protein fibres can also be dyed without a mordant when using Pomegranate peel due to its tannin content.

Once mordanted:

Add 100% pomegranate peel to 80degrees Celcius Water for one hour. (100% of the dry Weight of your Fibre/Fabric) If using powder, stir regularly or it will burn the bottom of your pan.

After an hour, switch of the heat and add the fabric/fibre. Leave to up to 3 days, until desired depth of colour. 

Wash, rinse, dry.

 Pomegranate Powder can also be used as a tannin and for printing when combined with Alum and Guar Gum.

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.

ANNATTO – ORGANIC, NON-ORGANIC & POWDERED

Botanical name: Bixa orellana
Dye colour: Yellow, orange, copper

Wool, silk, cotton and linen can all be dyed successfully with annatto. It yields warm yellows to rich orange tones and combines beautifully with other dyes such as cochineal and madder for extended colour ranges.

We offer three forms of annatto due to availability:
• Organic Whole Seeds – Wild harvested in Côte d'Ivoire
• Non-Organic Whole Seeds – Standard dye grade
• Non-Organic Powdered Seeds – Finely ground for quicker extraction and even application

Colour Range & Combinations

• Use with cochineal and cream of tartar for orange-red colours
• Pre-dye silk with madder, then add to an annatto bath for copper-orange
• Combine with tartaric acid to achieve yolk yellow

The dye is not very lightfast and may need to be refreshed after a few years. However, blending annatto with cochineal improves durability.

Basic Recipe for Yellow

100 g wool or silk, mordanted with 15% alum and 10% cream of tartar
100 g annatto seeds

1. Soak annatto seeds overnight with 10 g soda ash
