I recently read a blog post by Mari at Gather and Grow, she had dyed with turmeric using solar dyeing and without any mordants. I had a look around in my spice rack and found a jar of turmeric powder that had expired four years ago. I decided to have a go with that. I used mordanted wool because that’s what I happened to have (alum and cream of tartar) and I also used heat. I heated the water and mixed the turmeric powder into it. When I added the wet yarn the dye immediately dyed the yarn and I only let the yarn be at the dye for 15 minutes. I used the the dye again and dyed another 100 g skein of wool and it came out exactly the same colour. Turmeric is strong stuff! I feel like a much less turmeric would have been enough and that I could still dye a lot of yarn with the dye. I have it saved it case I want more. The only downside is that the smell stays quite strong in the yarn, even though I rinsed it a lot.
During my summer of natural dyeing I have found many plants from which you can get similar kinds of shades of yellow and green. Usually white yarns turn to yellow and grey yarns to green. I have collected some of them in here. All the yarns displayed have been mordanted previously with alum (read about it here.) I used the same technique as I did when dyeing with lupine (read about it here.)
I collected the cow parsley early in the summer when they were blooming. The result was not the most intensive one but still pretty.
Both meadowsweet (on the left) and fireweed (on the right) were collected early in June when they were not yet blooming.
I did a little weekend trip to the summer cottage and dyed with heather for the second time. I was curious to see what the difference is when I use heather from the beginning of June and from late August.
I don’t think this is the most scientific of experiments, but I did collect heather from the same place I collected the last time and I also used the same wool yarn. The yarn on the right is from the early June and the one on the left is from the middle of August. The colour was definitely more intensive in June, but the second colour is still beautiful.
I also coloured grey wool yarn and the result was beautiful green colour. Heather has quickly become one of my favourite plats to use in natural dyeing.
I have noticed that this Norwegian wool yarn (Viking Naturgarn) repeats the colours really beautifully. I mordanted the yarn beforehand with alum (read about it here). Before starting to boil the heather I let it soak in the water overnight, after that the process was similar to dyeing with lupine (read about it here.)
I took class on natural dyeing in the beginning of the summer and I though I share some of the things I dyed there. All of the plants I used for the colouring where collected in the beginning of June. Beginning of the summer is a great time for plant dyeing because the colours are more vibrant the earlier it is in the plants growing season (at least here in the north). The yarns I used where all 100% wool yarns and they were mordanted with alum. Read about mordanting here.
I used about 280 g of heather and dyed 108 g of wool yarn. First I soaked the heather in water over night. Then I boiled the heather in the same water for two hours. After that I dyed the yarn by boiling it in the sifted colour liquid for one hour.
For these yarns I used the liquid dye that was made out of onion skins. This was the third time that liquid was used. I added 3 g of madder powder and 1 g of cream of tartar to the liquid and I dyed 40 g of yarn. This really brightens the orange colour up. Check out my post for dyeing with onion skins here.
I used 319 g of birch tree leaves and dyed 73 g of wool yarn. You do need a quite a lot of leaves for dyeing a lot of yarn. I boiled the leaves in water for two hours and then I dyed the yarn by boiling it in the sifted colour liquid for one hour. To get a bright green colour like this, it’s important to use early leaves from the beginning of the summer.
I think onion skinss are amazing. It’s incredible how much colour they have in them. I used about 115 grams of onion skins to dye these yarns. I got the skins for free from my local supermarket. I might have gotten couple of strange looks while I was going through the onion box, collecting loose onion shells but it was definitely worth it.
I let the onion shells soak in water for one day before boiling them (in the same water) for two hours. For dyeing I used a variation of old wool yarns that I had mordanted earlier with alum. After shifting the dye bath I boiled the wool yarn in the dye bath for one hour (I kept the temperature at about 80 °C). After that I rinsed the yarn. Onion tends to release a lot of excess colour so it’s good to add some vinegar to the last rinsing water. I used wool yarns that I had previously mordanted with alum.
The first yarns on the left are from the first dyeing batch (88 g). I saved the dyeing liquid and dyed another batch of yarn in it(100 g). This batch is the yellow one in the middle. After that I used the colour liquid for the third time but added one teaspoon of madder powder and half a teaspoon of cream of tartar. These are the yarns on the right(77 g).
I think this is a good example of how different yarn qualities effect the dyeing result. I used both white and grey coloured yarns. With white yarn I got lighter oranges and yellows and with grey yarn stronger oranges and greens. I used ordinary onion shells but I also want to try red onion shells. I hear you can get a beautiful green from them. Has anybody tried red onion skins?
