🌿 INDIGO WEEK

INDIGO WEEK SUPPLY BUNDLE

A complete set for working with indigo vats

This bundle has been put together to support the live vat making sessions during Indigo Week — and to allow you to continue working with indigo beyond the sessions.

It includes all core materials needed to explore three different vat types:

  • fermentation vat
  • mineral (iron) vat
  • organic (fruit sugar) vat

🌿 DESIGNED FOR PRACTICE

This is not a one-off kit.

It is designed for:

  • building and maintaining working vats
  • comparing different vat types
  • developing your own indigo practice over time

📦 WHAT’S INCLUDED

  • Indigo (natural) — 150g
  • Iron (Ferrous Sulphate) — 100g
  • Lime (Calcium Hydroxide) — 250g
  • Fruit Sugar (Fructose) — 125g
  • Madder, ground — 200g
  • Wheat Bran — 100g
  • Potash — 500g

🌿 WHAT THIS BUNDLE ENABLES

With this set, you will be able to:

  • create and maintain a fermentation vat
  • work with a mineral (iron) vat
  • explore an organic fructose vat
  • compare behaviour, colour and reduction methods

🌿 FOR INDIGO WEEK

This bundle has been assembled specifically to accompany:

👉 Indigo Week — Join Us for a Live Online Indigo Journey

While participation does not require the bundle, it allows you to:

  • work alongside the live sessions
  • follow the vat development step by step
  • continue working after the sessions

🌱 CONTINUE BEYOND

The materials included are suitable for:

  • ongoing vat maintenance
  • further experimentation and refinement

🌿 IMPORTANT NOTES

  • This bundle does not include fabric or yarn
  • Indigo vats can be used with your own fibres and materials
  • Please follow safe handling practices when working with dye materials

♻️ APPLEOAK APPROACH

This bundle reflects a process-based approach to indigo:

plant → pigment → vat → fibre

Working with different vat types is central to understanding indigo — and this set supports that journey.
