I made a large batch of oak gall ink this summer and I had a jar of watered down henna from dying a friends’ hair. I wanted to experiment with making a scarf so I got white cotton and then I tied it up with rubber bands. I added more coffee to the henna mixture and then soaked it overnight. I then got the oak gall ink out and added some to the dye mixture and soaked it another couple hours. The result was really cool looking and natural. I haven’t finished this into a scarf yet but will do so soon and wear my creation!
