To a medium saucepan, combine the ingredient (or two) with the water. Bring the heat to medium-high heat and cover the pot. Boil for 1 hour, mixing every now and then. Turn the heat off and uncover. Allow to cool for about 10 minutes.
Then dip the linen in and allow to soak however long you like (20 seconds to a few minutes). Wring and twist and allow to air dry. Try to dry flat (any creases can show in the dye). Use an iron or steamer, as needed.
