I have experimented with dyeing fibre or yarn three times so far. I can't really say any of it has been a success. Attempt two and three were an attempt to rescue some Merino roving that failed to take on colour in a mixed berry dye bath. The yarn I dyed was pretty awful, but the roving was even worse, an awful bluey, browny pink colour. To be positive I invented aroma yarn as even after rinsing it smells very Tutti frutti.
I used my very old slow pot and 'cooked' the wool on medium for about six hours with the colouring added. Then I let it cool in the pot. No stirring because I did not want to make felt.
