Natural dyes are not like synthetic or chemical dyes. They can fade overtime. All of the the items made by Articulated Studios are pre-treated to improve the lifespan of the dyes.
It is recommended that naturally dyed items be washed by hand in cold water. Allow to air dry. Iron lightly on low setting.
Note: Most store bought detergents are designed to remove natural dye. They are also pH shifters so they can also alter the color. Use a gentle or pH-neutral detergent such as Synthrapol when washing.
