Today, we’re thrilled to announce an entirely new family of yarns: Henorius, by Garthenor Organic. We’ve long held an ambition to expand on our range, but we knew that to achieve this, it had to be done just right. We’ve been developing Henorius for just over a year, and we couldn’t be happier to finally be sharing it with the world.

The planning of this entirely new brand has been an enormous undertaking – it represents a number of “firsts” for Garthenor. New partners, new fibres, and biggest of all – colours. Since we began in 1998, Garthenor has only ever produced entirely undyed yarns, offered in a broad palette representing the natural beauty of the British landscape. Henorius, on the other hand, leaps into the dye pots to embrace a launch collection of 25 solid shades and 5 marls.

Henorius will be available for the very first time at Edinburgh Yarn Festival 2018. Stay tuned for pre order and stockist information.

Why ‘Henorius’?

We’ve made the decision to keep our two yarn families – Garthenor & Henorius, by Garthenor Organic slightly separate. Throughout the development process, we’ve felt that they represent two different approaches to yarn – though each just as fabulous as the other!

Despite being slightly separate, at all shows and events following the launch at EYF’18, we’ll have both Garthenor and Henorius yarns available on our stand.

“Garth Henorius” is thought to mean a view over the garth (a rocky mound), and over the years was shortened to “Garthenor” – so Henorius felt like a natural fit as a name.

“Romwarth” Blend*

Our initial yarns will launch as a creation from one of two bases. The first of these will be available in a range of yarn weights, all worsted-spun. In the worsted process the fibre is combed into a wonderfully smooth and even top before spinning, and so ends up silkier and with more lustre than the woollen process.

“Romwarth” will be made up of 60% Single Farm Polwarth from the Falkland Islands and 40% Single Farm English Romney, from the South of England.

Pure Lambswool*

The second base will be a deliciously soft and springy Romney lambswool, which will be woollen spun. The woollen process keeps all the fibres jumbled and traps more air, making them bouncier and warmer than worsted spun. All the current crop of Garthenor yarns are woollen spun, and the Pure Lambswool will be spun so that it’s interchangeable with these in weight and length.

Pure Lambswool will be 100% Single Farm English Romney Lambswool, from the South of England.

* Romwarth & Pure Lambswool are just our description for the bases – not what the actual yarns will be named!


As with everything we produce, all Henorius yarns will be 100% certified organic at every single process, from sheep to shelf – no compromises, anywhere.

This means that every step in the production has been independently inspected to Global Organic Textile Standards.


“Does this mean you won’t be producing your undyed yarns any more?”
Not at all – in fact, we’ve got some beautiful new breeds, blends and shades to share with you throughout 2018.
