What You'll Learn

Discover new ways to add complexity and richness to your hand-dyed colourways using acid dyes and protein-based fibres. Building upon the skills and knowledge in our Dyeing Intentional Colour course, this course will explore:

  • Developing a deeper understanding of colours and colour theory, focusing specifically on what happens when colours are mixed and learning to create or avoid muddy hues
  • Creating glazed, layered, and tonal hand-dyed colour effects through immersion dyeing and the addition of delicate resists
  • Manipulating the variables of dyeing to produce non-repeating multi-coloured yarns with a low water immersion technique
  • Learning how to create handpainted yarns and spinning fibres for repeating colour sequences
  • Understanding and creating different self-striping colour sequences
  • Applying these dye techniques and methods to knitted sock blanks to produce even more hand-dyed effects on yarn
  • Finding ways to make the dyeing process more safe, efficient, and productive through equipment, studio setup, and preparation.


Create complex, layered, multicoloured, and handpainted yarns and spinning fibres through different dye application techniques

Who This Class is For

This course was designed to be an intense and in-depth exploration of hand-dyeing techniques for dyers who are passionate about precision dyeing and hungry for the next step. If I taught this course as a live event or a retreat, it would likely be a 5-day long workshop! By teaching through these videos, I’m excited about the opportunity to reach you where you are right now with your dyeing.

I know that when I started learning how to dye yarn, my appetite for new ideas and techniques was insatiable but there was not a lot of resources for me to go to. After the past 13 years of exploring dye techniques, I’m happy to share the things I’ve learned with new and experienced dyers so that more creative spirits get inspired to enjoy the transformational power of beautiful hand-dyed colour.

What You'll Need to Get Started

Dyeing can be as simple as using a single pot and a heating element, but we’ve created a comprehensive list of tools and supplies that we use in this course and that might be helpful to build or augment your dye studio set up. Included here is a list of suppliers for yarns, fibres, dyes, and knitted blanks. As well, many of these items are available in our online shop here to get you started.

Why This Class is Different

This course builds upon our foundation of creating intentional colour and explores hand-dyeing techniques to add that elusive depth and richness that makes colours sing.

Through 47 video lessons in 8 modules and over 5 hours of content, you can walk beside me as I dye yarn in sixteen different examples. My dyeing style involves working with precision and intention as I create colourways, so you can join me as I lead you through the simple math calculations that are so helpful in preparing for an efficient and effective session in the dye studio.

Frequently Asked Questions

When does the course start and finish?
The course starts now and never ends! It is a completely self-paced online course - you decide when you start and when you finish.

This will give you a good idea of what our video lessons are like. If you are still unsatisfied with your purchase, please contact us in the first 30 days and we will give you a full refund.
What kind of supplies or equipment will I need to take this class?
You'll need some acid dyes (available from ProChemical & Dye or Dharma Trading Co.), undyed protein-based (like wool or silk) knitting yarns or spinning fibres, and some heating equipment (pots, pans, portable burner or something similar). We have the complete list of tools and supplies available for download to students.
I don't care to be so precise with my dyeing. Is this for me?
Absolutely. Sometimes, I like to be more carefree with my dyeing sessions as well! The information that I share in this course is about giving you a foundation to understand how colour is created with acid dyes and how you can manipulate the variables to produce the effect you want. Once you know these fundamentals, you can be more intuitive and play with colour more freely without needing to calculate all your dye quantities. It's all about strengthening your knowledge base so you can be a more confident dyer and colourist!
