In a double boiler (or a bowl on top of a pot of water) bring water to a boil.

Once the water is boiling, reduce the heat to a simmer.

Add the soy wax flakes and stir until fully melted.

Remove the melted wax from the heat and add essential oils if using, and stir.

While the wax is melting, adhere the candle wicks to your jar. Use glue, super glue, or a bit of wax to secure the wick.

Pour the melted wax into your containers.

Hold the wick straight up with a clothespin or a chopstick or pencil.

Let the wax set overnight and trim wicks to 1 inch.
