Fill a 10-ounce soap dispenser about 80% full with water. (I use plain old tap water - you can use any water you choose.) This doesn't have to be exact. Add the castile soap and vegetable glycerine. Then, add your preferred Young Living Essential Oils until you reach the desired aroma. For a fall scent, I used 8 drops each of YL Thieves Essential Oil and YL Orange Essential oil. Screw on the top, give your soap a good shake and enjoy!
