Dye wool with fungus

We have had a lot of rain recently (and our tanks are full) so of course all the fungal spores in the soil have taken advantage of this and popped up mushrooms and shelf fungus everywhere. There is a lot of information online about dying wool (and other protein fibres) with fungus, so I decided to have a wander around and see what I could find to experiment with.

In the bush around our humpy I found many kinds of fungus after just a cursory look; I haven't tried to identify them as I am mostly interested in using them for dye. It's not a great idea to eat mushrooms you aren't able to identify, and I won't do it. I will also be using gloves to process my collected bounty, just in case they prove to be toxic.

Below is a collection of photos of the fungal and lichen life I found in my little adventure.

The plan is to dry most of the current harvest for later experimenting. I couldn't resist trying one little experiment though.
I used a lovely brown shelf fungus I found on a dead tree with two tablespoons of washing soda to make an orange/ yellow dye pot. I simmered the pot of water, fungus and washing soda for an hour. Then I plonked in some merino home spun yarn and let it all cool overnight.
After rinsing and drying I ended up with a golden yellowish coloured yarn that my daughter has named 'You dirty sheep', the name doesn't do justice to the colour which is actually quite beautiful. I can't wait to do some more experiments to see what I will get.

The little shelf fungus on the left gave the muted golden yellow of this yarn.

Natural dye experiments- logwood on cotton and linen

Another natural dye experiment....
I have been looking for a natural purple dye for a while and came across logwood as a possible candidate. There are some problems with using it however; it is not really environmentally friendly as it uses the heartwood of a tree (destroying the tree in the process of gathering dye material is not really friendly) and it is exclusively an American product (so a lot of miles of shipping are racked up in it's cost); it is expensive (see previous problem) and hard to find.

But.....I really love the purples and browns it gives in the dye vat.

Logwood has been used as a dye since the 1600s and has been expensive and valuable since it's discovery. Apparently pirates loved to hijack a shipment of logwood sawdust on it's way from Jamaica to Europe. After using the dye, I can understand why.

Not having access to a pirate ship, I had to resort to buying some online (possibly from pirates). It then sat in my dye box for a month or two waiting for the perfect project.

I had been given some 'teacher clothes' by a friend (thanks Louise), they are all cotton or linen and very high quality clothes...but, they are all either white or pastel colours (I can't wear pale colours, they end up VERY dirty). I decided to try out my newly purchased logwood dye on them.

First step was to mix up the dye;

Logwood dye in it's jar. I mixed it at a rate of 1 teaspoon per litre of water.

Then I mordant-ed all the clothes with Aluminium Acetate and plopped them into the dye bath. I left them there on the wood heater for a few hours and then took the pot off to cool. The results were a set of mottled purple clothes which I love. I think the mottling comes from my not having enough mordant in the mix; some areas attracted the dye more than others because they had more mordant on them.

Cotton and elastane shorts


This linen skirt was originally pale blue. Over dyeing has given it a beautiful depth.

Of course I won't be able to wear them together (I would look like an over ripe eggplant), but they should add interest to an outfit.
I also had an old cotton hospital sheet (these sheets are virtually indestructible and must have Kevlar somewhere in their makeup; perfect for work) which I mordant-ed and dyed as well. The sheet then became a pair of elastic waisted pants. The dye bath was getting exhausted by the time I got to the sheet so I ended up with mottled beige and purple, to add some interest I mixed up a tiny bit more dye and flicked it onto the wet material with a paint brush (the purple spatter patterns).

They turned out pretty well I think

So now I have a lot of purple mottled clothes. I love the colours I got from this dye bath, but I won't be buying it often because of the aforementioned unsustainability of the dye stuff.
I have concerns about the light fastness of the clothes too, but time and wear will tell. Of course I can always dye them again (or with a different colour) if they fade....I love natural dyes.

Natural dye experiments - gardenia powder and alum

My natural dye experiments have continued into the garden; I recently tried gardenia powder to dye some 100% wool yarn, and the results were spectacular. I found a listing for gardenia powder in my favourite dye stuffs shop (for the bits I can't make myself); KraftKolour, and having a few dollars to spend (thanks to selling some home spun cotton yarn) I bought it. I was really curious to see what sort of colour I could get from a common garden plant. My mother recently found a mixed bag of pure wool in a second hand shop in white which she gave to me (thanks Mum), so I had a decent amount of yarn to play with.

The process is really very simple; weigh your fibre; mine was 123g, gather your equipment and off you go.

My equipment and supplies.

The yarn my mum found in a second hand shop.

I decided to mordant my yarn with alum at a rate of 15g per 100g of yarn (and yes I did use a calculator to do the maths).

I weighed up my alum and popped it into my yard dyeing pot with some water.

Once I had the alum mixed in fairly well with the water in my dye pot I plonked in the yarn in handy skeins (all tied up with cotton yarn so I didn't end up with a tangled mess). I bought this pot to a simmer then turned it off and let it sit while I made up the dye.

My dye was mixed at a rate of 6g per 100g of yarn (yes...calculator again) in a big stainless steel pot. The dye comes as a sort of bluish powder but the dye pot goes a dark blue colour. I heated this water up almost to a simmer (close enough to the same temperature as the yarn in the mordant).

Then I fished out my skeins (using my trusty serving fork, that is only used for fibre work) and lowered them into the dye pot.

The yarn going into the dye pot. How pretty is that.

After about ten minutes it was this colour.

I turned off the heat on the dye pot and let the yarn sit until it was completely cool. Actually it sat in the dye until I remembered what was in the big pot on the bench while I was washing up that evening.
Then I rinsed the yarn in cool water, wrung it out and whacked it against a post to separate any felted strands (force of habit) and hung the skeins up to dry.

Drying skeins
As you can see the different brands of yarn took the dye up at varying rates. I love the different shades though and they are all very pretty.

My dried and wound up gardenia dyed yarn.

I am so impressed with this colour I think I will get spinning and make some merino home spun to try it out on; maybe I can get enough of a single shade to make a jumper or something.

Dyeing yarn with indigo

Indigo dye vats have fascinated me for a while now; the magic that happens when you add fibre to a yellow green dye pot to get a blue result puzzles and excites me. Recently I found the time (and courage) to have a go at it; thank you Sandy for the push.
First I did a fair bit of research about how indigo is made from the plant. Indigo is made from the leaves of indigo plants which are fermented, soaked in a caustic solution and then dried to produce the blue 'rocks' or powder that comes in the mail for me to play with.
Once I had my little pots of powders and chemicals, I downloaded the instructions for use and got to work...

I decided to dye some hand spun cotton as I had an order for cotton gloves.

I gathered up pots, scales, utensils, indigo, caustic soda
sodium hydrosulphite, yarn and a sense of adventure as per instructions 

I added the caustic and hydrosulphite to the 15 litres of water

I added the indigo to the dye pot

It made a big pot of blue at first, so I put the lid on and waited.

Until the pot was yellow/green with a copper scum on top.
This photo doesn't show the copper scum to full effect, but it is there.

I decided to experiment with cotton, merino and suffolk yarns (because I had those lying around).

Better late than never, I found a pair of rubber gloves.

I made a tiny skein to test dye first, this one is cotton.

Well, it came out blue.

So I tied the skeins to a bit of wood and lowered them into the pot.

They went a lovely shade of dog vomit green/yellow at first.
 The copper scum shows up much better in this photo.

I lifted the yarn out and waited for it to turn blue

Which it did

Then faded to a much lighter blue as it dried.

That was the batch that worked......the story of the vat that didn't is much the same until the 'lifting the yarn out' stage then I found that my four skeins of cotton yarn (which take forever to prepare and spin) had turned into a big blue jelly fish in the bottom of the vat. I eventually figured out that the 150g of caustic recommended in the instructions was just too much for the yarn and it melted. The second lot I cut the caustic down to 15g (about a tablespoon) and it worked well; must have been a misprint.

In ancient times indigo dye vats were made using stale urine (because they didn't waste anything). The processed indigo was stuffed into a cloth bag and lowered into a big tub of stale urine and left to ferment for a week. Cloth and fibre was then soaked in the vat for various lengths of time then rinsed (really well, I would think) and left to dry in a breezy place. This kind of dyeing vat is called a sig vat. I will try this method at some point, when I can afford more indigo dye.
Maybe I should try growing some indigo plants, what do you think?
Have you tried indigo dyeing? What was your experience?
