Before you begin, stick one side of the wick sticker on the bottom of the tab of the wick. Stick the other side of the sticker to the bottom center of the jars.
Cut a small hole or slit in the center of a strip of masking tape that’s longer than the width of the jars. Thread the wick through the hole and stick the tape across the opening of the jar, so the wick is centered in the middle of the jar. Repeat this with the remaining jars.
In a double boiler, or a heat-safe bowl nestled on top of a pot of simmering water over low heat, combine beeswax pellets and coconut oil.
Heat until completely melted, about 30 minutes.
Turn off heat and add essential oils, if using. Stir together to combine (I used a popsicle stick so I can throw it out afterwards).
Pour the wax into the prepared jars.
Let cool for at least 12 hours.
Cut the wicks to about 1/2 inch and remove the masking tapes.
Light and enjoy!
