Gather rose petals each day, until you have an ample amount to make your potpourri. Place on a screen and let dry.
Place all dried petals in a jar with a tight fitting lid. Add 5 drops of Rose oil or Geranium oil and 5 drops of Glycerine.
Keep adding dried petals from time to time. Other fragrant flowers, such as honeysuckle or orange blossoms, can be added if you like. When the jar is full, sprinkle a little salt over the petals.
Shake the jar every day for two weeks and then add one fourth once of each of the following: Orris root powder, nutmeg, cinnamon and allspice. Keep the jar tightly covered.
Rose oil, geranium oil and glycerin can be purchased from druggists and health food stores. Orris root from craft stores.
