You can add additional flavors, but I find that scents get confusing if you add more than four to a recipe. Mix the essential oils into the soap until well combined.
Pour the soap base into your soap mold. Tap gently on a flat surface to remove any air bubbles. Dabbing a little rubbing alcohol on the top helps knock out the ir bubbles, too.
Wait 24 hours for the soap to dry before popping it out of the mold.
