SCHEDULE
-

A two hour session for all the group members to meet and set intentions for the year going forward.
Hosted by Natalie Stopka and Isobel Denton
-

Alder cone yields a rich, transparent, amber colour. When oxidised and combined with metals and modifiers, it is possible to deepen and darken the colour, and increase its opacity. Like oak gall, its tannic acid reacts with iron water to produce a permanent black.
For this workshop David will discuss the versatility of alder cone ink compared to oak gall ink and its ease of preparation. David will demonstrate how to cook alder cones to make a variety of different colour inks; working with different modifiers and equipment to alter the ink and demonstrate painting techniques he’s developed. David will discuss a selection of his works in ink and this will be followed by a discussion.
-

Privet berries are one of my favorite sources for making a local blue color.
My neighbor has a privet hedge along their driveway and graciously lets me pick them in the spring.
The berries ripen over the winter season here in Portland, Oregon. The color in the berries is most intense in March and April.
I’ll show you how I use privet berries in the studio, from ink to lake pigment. We’ll also cover the history and ecology of privet.

When starting her journey with botanical printing, Elisabeth stumbled on a tall Cotinus (Smoke bush) plant in a Scottish car park she was regularly using.
The large red leaves proved good printers and made strong marks with Elisabeth’s then rough method. A deep red mark was a constant and it never failed. Printing Cotinus leaves on a daily basis through a whole season gave her a chance to appreciate the seasonality of the colour making, reading about it in historical dye manuals she associated it with early mordanting of the Mediterranean cloth dyers and the rich tannin content of its stems. Six years later the discovery journey is still on and from printing the leaves, creating tannin bath, extracting pigment and much more, Elisabeth feels her creative journey has only just begun with the red leaves.
In this session, she will share how the plant through a slow and constant dialogue, has taught her much about natural dyeing, about respecting the seasons, about understanding the deep relationship between soil and plant, about pushing the boundaries of discussion and collaboration with one’s own local source of colour.
-

Weld proclaims its usage by its common names: dyer’s weed, dyer’s rocket, and dyer’s mignonette. This biennial produces gleaming lemon yellows - beautiful on their own and mixed with other dyes. Historical dyehouse recipes give these mixed shades evocative names such as vert perroquet, cannelle, vert d’olive pourri, and feuille morte: parrot green, cinnamon, rotten olive green, and dead leaf. Readily grown on sandy, rocky, or chalky soil, weld sends up towering flower spikes in its second spring. It's a companionable garden plant, ceding ground to others after setting copious seed early in the growing year. This session will discuss the cultivation, history, and applications of weld.
-

In this session, Isobel will share how she grows and uses this generous little plant within her practice, from dyeing old cotton fabric scraps and waste paper to creating natural watercolour inks. She’ll explore how the dyed fabrics and papers can then be repurposed into new handmade paper, combining them with the spent chamomile flowers themselves, giving this little ray of sunshine a life beyond the dye pot.
Isobel will also show how the colour of the paper pulp can be modified to create different shades, and how the extracted dye can be used as a beautiful watercolour ink.

Since discovering a brief mention to Turnsole, Chrozophora tinctoria in Joumana Medlej’s book ‘Inks a Paints of the Middle East’ in 2023, a kind of frenzied obsession followed. Curious to what this plant was, and to its historical use in the Western Medieval Illumination tradition, has led Annie to a research dive into the veiled practice of its colour extraction and processing, eventually leading her to a tiny village in the south of France with a fascinating link to this plant and its colourant.
She has uncovered it’s strange and often sad history, experimented with wild harvesting and historic processing, is currently attempting to grow the plant over two sites in Ireland and is continuing her research in working with this very interesting pigment. In this session, Annie will detail the history and uses in Europe, share her ongoing findings of hunting for and working with this elusive transparent mauve colourant.
-

Indigo holds something of a mystical aura, being a plant that comes with such a wealth of history, culture and stories. Sarah has been captivated with its beautiful range of colours since taking a natural dying and weaving workshop in Laos nearly ten years ago. Now by growing it herself she is constantly learning more about this beautiful plant.
In this session Sarah will simply share with you how it is used within her practice, making sure to utilise the whole plant in different ways. Her ethos is always to waste as little as possible using the leaves to extract colour, make paper and the stems to weave tiny baskets and even the chaff from collecting the seeds can find a use. It is a useful and magical plant!
-

This session explores the history, botany, and personal insights behind yarrow (Achillea millefolium). Tracing its journey from seed to full bloom in her dye garden, Greta will share the story of discovering this extraordinary plant and its rich background.
Often wild, hairy-leaved, and easily overlooked, yarrow grows from a modest leaf into an abundant plant with gifts that extend far beyond color. It attracts pollinators, deters garden pests, and serves as a subtle, essential companion for both the dye garden and the surrounding ecosystem. During the session, Greta will demonstrate how to extract color from yarrow and adjust its tones using pH modifiers to create natural ink.
-

This session explores the history and chemistry of madder root, tracing its use from ancient textile dyeing to the transparent red lakes favoured by later painters. We will focus on the development of madder lake pigments and the role of colour-makers such as George Field in refining methods for producing clearer and more durable reds. The presentation will introduce the principal colourants found in madder, including alizarin and purpurin, and explain how extraction conditions, metal salts, and pH influence hue, stability, and permanence.
A live demonstration will show the preparation of a madder extract and its conversion into a lake pigment using alum and an alkali, illustrating how soluble dye molecules are transferred onto an insoluble substrate. We will briefly compare how selected metal salts can shift madder toward warmer, darker, or more violet tones, using historical samples where appropriate. The session will conclude with a simple paint test of the finished pigment, examining its transparency, glazing qualities, and characteristic soft red and rose tones.
-

A personal and practical exploration of cherry trees (and other closely related prunus species, such as plum). This small to medium sized tree can be easily spotted by its abundant blossom in spring, late summer fruits and frequent gummosis (gummy sap leaking from fissures which looks like honey or amber).
Cherries are planed in urban environments the world over as well as being found wild or naturalised, widely across the globe. We will look at their history in art and design, how Sakura (cherry blossom) is sometimes feverishly revered in Japan, how it crops up frequently in folk, jazz and pop music, and how the fruits have long been used both in fine carving, wood turning and in story and metaphor.
Then we will practically explore making colour from the fruits, leaves, petals, bark, sepia ink from the decorative cultivar with purple leaves, watercolour medium from the exuded gum and charcoal from prunings. Recipes, methods and troubleshooting will be shared.
-

A two hour session for all the group members to share their reflections on the past year together and set intentions for the future.
