Place chopped soap and broken crayon in a microwave safe dish (I prefer a glass measuring cup) and microwave until soap is fully melted (30-45 seconds). Stir until crayon is fully dissolved.
Add the essential oils. Stir.
Place mold on plate and pour in the melt and pour soap mixture. Set out to cool. If you wish to make more soaps, just place in refrigerator to cool.
Pop out the soap.
Notes
Recipe is perfect for making one bar in this cute clover mold or any 3 oz. mold.
