THISTLE
100gCook the plant material in water for one hour.
Put 50g Wool (treated with 10% weight of fibre Alum over night) into the dye bath, heat it up and let it simmer for around 1 hour.
Then covered it with a lid and let it soak over night.
Generally during the nights cover the pot with either a lid or some textile, so nothing is flying into your pot (like pollen...) and changing the color outcome.
