Pour the diffusing perfume into the glass decanter. - For a light fragrance diffusion, only use 10 reeds & half of the perfume. - For an intense fragrance diffusion, use all of the reeds and all of the perfume. Place the reeds into the decanter in the form of a bouquet. Thanks to its diffusing system, the fragrance absorbs into the reeds much like water delicately ascending into the stem of a plant.
