Set your wick in place by centering it inside your container. (If you did not purchase wicks with tabs or plates, make sure to connect them beforehand.) Make sure that the wick plate touches the bottom. Then, wrap any extra wick around a pencil. Use the pencil to keep the wick centered and upright.
In the saucepan on low heat, pour in the wax and stir frequently. Once the wax is melted, remove it from heat and let it cool slightly.
Add and stir in the essential oils of your choice, about 20-30 drops per candle. Adjust according to your preference for scent strength.
Carefully pour the scented wax into your prepared containers. Leave a bit of space at the top to prevent spillage. Allow the candles to cool to a solid state. Avoid moving them while they're setting
Once the candles have fully cooled, trim the wick to about 1/2-inch above the wax surface.
