Melt the wax using a wax melter or a double boiler. Note: the amount of wax will vary depending on the size of the mug or jar you are using. 

Once the wax is melted, pour just a bit into the jar and roll it around to coat the sides. You don't want a lot, just enough to cover the sides. Then, toss in your coffee beans and roll them around evenly so that they stick to the sides. Tip: If you use too much wax to coat the sides, the beans will just slide down to the bottom. If this happens, let it harden up slightly, then press the beans against the sides.

Add a touch more wax to the bottom of the jar and press your wick into it in the center. Let the wax harden completely.

Now, add your fragrance to the melted wax, stir well, and carefully pour the wax into the jar or mug.

Center the wick at the top of the candle and wrap it several times around a bamboo skewer or a pencil to hold it in place while the wax hardens.

Allow it to cool completely before trimming the wick.

Light the candle and take in that lovely aroma!
