Natural dyes and Preservation Methods - brine and wine

The following article was written for Garland Magazine and below is only part of the original story but I have added images to the tutorial. 


Natural dyes and Preservation Methods

My natural dyes journey began in 2002 when I wandered into the yard of some weavers in a village in the north of Laos. At the time, I was consultant  doing research for UNICEF.

This was a life changing moment, while watching the skilful hands moving through the warp and weft that I began a deep appreciation of the labour that went into weaving such beautiful pieces. 

I then spent the next three years learning about the traditional craft of natural dyeing with several master weavers and dyers whose knowledge had been passed down to them from their mothers over many generations.

Something that fascinated me while visiting the ethnic hill tribe markets in Laos and Chinatown was seeing the displays of herbal medicines and tinctures. 

The hill tribes were mostly Hmong people who had traveled down to Vientiane from where they lived in high altitude. Their markets were random makeshift stalls, always located outside the regular markets. Everything about these tribes people was interesting for me. They wore traditional clothing that was handmade and carried their babies in beautiful hand embroidered cottons and hemps. They spoke their own language so we couldn’t  communicate unless someone could speak Lao. The products they were selling at the time were probably illegal or endangered animals that they believed could heal ailments. There were small bottles that had gecko like creatures floating in homemade alcohol that could literally knock your socks off as the alcohol content was more than forty percent!

On trips to Bangkok, I would visit Chinatown for the experience but also in search for antique clothing to try and replicate the intricate appliqués. 

There were many stores selling traditional Chinese herbal Medicines. They would have huge jars with herbal roots of medicinal plants or venomous snake preserved in alcohol. The stores were of course much more organised than those of the ethnic markets with dried herbal roots wrapped in bundles, parts of animals such as whole snakes, in jars and bottles steeped in alcohol.

In Traditional Chinese Medicine, therapeutic tinctures are often made by using alcohol as a solvent to extract the active ingredients of plants and allow them to keep for a longer period of time. The herbs which are carefully selected are steeped in the alcohol for some time before use.

The liquids in the jars and bottles were of different shades and over the years that I learned natural dyeing techniques, Khaisy, my weaving and dyeing teacher would add bottles of locally produced alcohol. She would tell me that it helped to fix the colours. 

I asked her if she had ever placed fabric in the jars with alcohol and dye stuff to which she said no because she could make alcohol herself. 

So I took this fascination of the preserved herbs in alcohol and have been experimenting ever since. 

When I returned home to Australia I made contact with professional chemists and biologists to understand what alcohol does and how it reacts with plants and animals.

For preservation and tinctures, alcohol is an excellent solvent for herbs, because it can extract the compounds and active ingredients that aren’t water-soluble, such as essential oils, alkaloids, pigments and resins. It’s also the only edible solvent that can effectively extract the ingredients required.

Alcohol is a preservative and gives herbal extracts a longer shelf-life. Some of the herbs in jars had been there for almost fifty years! 

Alcohol is the best preservative as they last for years! A good old whisky can outlive a human and it doesn’t freeze. 

Today, we are constantly being told to restrict alcohol as too much is not good for our health. 

Another preservation method I use for dyeing is the simple pickling technique. Pickling is one of the oldest preservation methods for extending the life of food, in a brine or vinegar. 

Here, Im going to share two simple preservation methods that I have been using to create colours for small pieces fabric scraps and some food waste. 


Please note: 

I have repeated and tested the techniques hundreds of times and created products for homewares without any problem. However,  the pinks created from the dyes in the samples are used for patchwork or products such as cushion covers or decorative items that will not be washed frequently. If you want to dye clothing, use different techniques with more substantive dyes. 


Materials needed:

Glass Jars 


left over white wine or alcohol 


pieces of fabric, must be natural fibres: cotton, linen, silk, wool 



Fresh or dried flowers with dark colours such as dark red geranium, hollyhock, red rose petals, dahlia’s.

Food waste: onion skins brown and red, decaying berries, passionfruit skins, purple carrots.


Gather all your equipment, materials and dyes you will be using. For the salty water brine method, any salt can be used. 



In image 1 - Im using sterilised old jam jars. In one jar, I have placed two heads of red rose petals and in the other, some onion skin, roughly skin of six whole onions.



Image 2 - Place fabric scraps or material in the jar


Image 3 - For the rose petals, I have poured in old white wine that had been sitting in the fridge for weeks.

For the onion skin, pour in boiling kettle water and make sure the contents are submerged. If there is fabric above the liquid this will create markings and uneven colour. Add a tablespoon of salt in the jar of onion skin jar. The salt helps keep bacteria from propagating. 


Image 4 - Place the lids on tightly and store in a cool dark place or the refrigerator if you have space. 

For best results, allow for at least three weeks before opening the jar. Please note that if you do these experiments in ( Australian ) summer, it is ideal to check on the jars as sometimes mould can form inside the jars containing brine liquid ( salty water).

Once dried, iron and the fabric is ready for your projects. The image below are double petal hollyhocks in brine for three weeks. The patchwork was made into a cushion.
