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.
