Woad is a member of the brassica family and happily grows throughout winter. Grows as a rosette, harvest the leaves as you would a cut-and-come-again lettuce, from the oldest leaves, discarding any that have browned.

Aluminium acetate is used for the mordanting of cellulose fibres such as cotton, linen and hemp. Use at 5-8% WOF.

Alum acetate is considered non-toxic, but working in a ventilated area and wearing a mask and gloves is best practice whilst handling this powder. I recommend keeping any tools used for this process separate from kitchen tools. Alum acetate may be safely disposed of in a municipal water system by pouring down the drain.

This material comes in a natural biodegradable cellophane. We recommend transferring this to a glass or plastic jar for long-term storage.

Symplocos is a natural, plant based mordant. The leaves are a natural bioaccumulator of aluminium, and when harvested and groundintoo powder, these made an effective mordant. it can be used on both cellulose and protein fibres at 50% WOF.

Note that Symplocos does impart a yellowish shade onto your fabrics, and will therefore affect your final dye colour.

Aluminium Triformate is a room temperature mordant for both cellulose and protein fibres. part of the alum family, it is a more recent addition of mordanting options for the natural dyer, gaining popularity (particularly with wool dyers due to its temperature requirements) for its low-impact process (water & energy saving). It produces similar results to that of alum acetate, and can be used with a pre-tannin bath to help improve dye fastness. use at 5-10% WOF.

Ferrous sulphate, more commonly known as iron, is used as a natural dye modifier, darkening (or 'saddening') natural dyes. It also can act as a mordant, to improve light and wash fastness for dyes,

Join us in our journey at home as we learn how to grow and process linen flax together!

Each packet of linseed contains approx. 2,000 seeds to provide a dense crop of flax over 1 square meter.

Please note, this flax has been historically bred to produce seed so its characteristics mean that it wants to branch and go to seed early. We can discourage branching by creating a dense crop (2000 seeds per square meter), and we should expect shorter plants than fibre-bred cultivars, but we should still get a good fibre length.

Clothes hold stories worth keeping. While we wait for the next dye season on our farm, we’re working with sustainably sourced natural dye extracts from accredited growers in India — continuing our commitment to colour that honours both people and soil.

** NOVEMBER 2025 COLOURS **
Lilac & Pōhutukawa
(NB: the Lilac colour way is not plant-based)

** HOW TO ORDER **
Because natural dyes only bond with natural fibres, we can only accept garments made from cotton, linen, hemp, wool, silk, or other natural materials.
We charge by weight, so pop a bowl on your kitchen scales to check how much your garment weighs before placing your order. Our current weight limit is 1kg per item.

** DEADLINE **
Please send us your garment by the 12th of November to ensure it arrives on time. We'll aim to dispatch your freshly coloured items by 29th November but it may take an extra few days during the Christmas market season.

** IMPORTANT **
We value the organic, imperfect, and evolving beauty of plant dyes. By sending your garments to us, you’re stepping into this living process. We trust that you, like us, see these variations not as flaws, but as part of what makes naturally dyed textiles special.

Aluminium Sulphate is used for dyeing protein fibres such as wool and silk. it can be used at 10-15% WOF (weight of fibre). cream of tartar can be used in addition to this mordanting process to assist with the bond of the mordant. it can also be used to mordant cellulose fibres in addition to a tannin bath.


Alum sulphate is considered non-toxic, but working in a ventilated area and wearing a mask and gloves is best practice whilst handling this powder. We recommend keeping any tools used for this process separate from kitchen tools. Alum may be safely disposed of in small amounts via a municipal water system by pouring down the drain.

Weld is an ancient dye plant, it is thought to have been used since prehistoric times and was produced prolifically in Europe through to the 19th century as the most common source of yellow dye (until the importation of quercitron from the Americas). Now one of the most iconic sources of yellow dyes in the world, known for it’s excellent lightfastness.

Dye colours obtained: The plant is rich in luteolin, a flavonoid which produces a bright lightfast and UV stable yellow dye. It can be overdyed with woad (or indigo) to produce ‘Lincoln green’ (a colour often associated with Robin Hood and his band of merry men!). Combine with iron to create a wonderful chartreuse, or with iron + tannin to create a rich olive green. Samples dyed at 50% WOF.
