Remove the cap from the bottle of isopropyl alcohol.
Use an eyedropper to add 10 to 12 drops of your favorite fragrance or essential oil to the alcohol bottle. Get creative and experiment with different oil combinations, but do not exceed 10 to 12 drops per 16 fl. oz.
Replace the cap tightly and shake the bottle gently to blend the contents together.
Pour the Lampe Berger oil into a small container or bottle with a tight lid, or simply leave the oil in the alcohol bottle.
Affix a label on the bottle or container to help identify the type of fragrance. Store the container of oil in a cool, dark location when not in use.
