We're excited to share a deep and practical exploration into natural dyes with Michel Garcia’s latest tutorial — his most comprehensive course yet.

This time, the focus is clarity, accessibility, and real results: 150 colors, created across a wide range of natural fibers, all achieved without relying on complex chemical formulas.

🌿 What You’ll Discover:

  • How to build your own color sampler — not just as a reference, but as a tool for creativity and consistency.

  • A practical method to dye cotton, hemp, wool, and silk with lasting, vivid results.

  • A palette that spans the traditional — indigo, madder, weld — and the surprising — like artichoke leaves.

  • Historical insights paired with modern ecological alternatives: inspired by centuries of expertise, refined for today.

Over five intensive days in the studio, Michel distilled years of research into 12 hours of clear, hands-on video instruction.

🧵 This Course is Made For:

  • Experienced dyers ready to refine their palette, revisit tradition, and push their results further.

📚 Along the way, you’ll also gain a deeper appreciation for the legacy of dyeing: the samplers of the Gobelins, museum tapestries that still glow after centuries, and the importance of naming and preserving colors.

✨ This is more than a tutorial — it's a gateway into a practice grounded in history, science, and creative potential.
