FERN

240g Fern, cooked for 1 hour in water.

60g cotton (treated with 20% weight of fibre: 12g Alum over night)

Heat the cotton in the dye bath with the Fern for up to 1 hour, then leave it in for 2 days.

*As there was nothing much happening I added Apple Cider Vinegar the second day, and left the textiles soaking in the dye bath for one more day.
