Time: The longer you let the bandana with the dye stuff and water, the darker the color will be.
Care: Hand wash with cold water and air dry.
Plant dyed fabric: Fabric dyed with plants will retain color and it will not wash away. Some changes with time might occur, depending on sun exposure and general care, but the fabric will not become white again.
