Place wax flakes in a double boiler or large glass measuring cup in the microwave.
Dip the end of the candle wicks into the melted wax and adhere to the center of the bottom of the jars. Wrap the wicks around chopsticks or skewers set over the top of the jar to keep the wicks centered.
Once wax has almost melted, remove from heat and stir to finish melting. Add the spices and stir well. (Some will sink to the bottom of the jar.)
Pour the wax into the prepared jars, leaving a little space at the top. Let cool completely.
Trim the wick to desired length and use or give as a gift.
