Place soy wax and coconut oil in a microwavable bowl. Microwave in 30 second increments, stirring in between, until the supplies are melted. If you use a crayon, remove the paper and place it in the bowl with the wax and coconut oil and melt.
Stir in 20 to 30 drops of essential oils into the melted colored wax.
Pour the wax mixture into a silicon mold and allow to harden overnight. Once they harden, pop them out of the mold. The wax color will lighten while it hardens.
