Combine the soap and oil in a double boiler over medium heat and begin to melt. Add in the orange and lemon zest.

Stir every so often but know that the soap won't melt solid. You'll know it's done (about twelve to fifteen minutes) when the oil is melted but the soap still looks slightly "chunky". 

While the mixture is melting, divide the tablespoon of cane sugar into the bottom of the molds. You just want a light sprinkle.

Then pour the white sugar into a large bowl )if using essential oils and not zest, add them into the sugar and mix well). Add remaining zest into the sugar.

Once your oil mixture is melted pour the it into the bowl of sugar and mix with a fork until all of the sugar is coated and wet. This is where you can add any color you like too.

Using a spoon portion and press the sugar scrubs into the molds (press down hard so they hold together).

Place the molds in the fridge for thirty minutes to set.
