Once the glass bowl has cooled, use tape to hang the skull from the bottom of the bowl.
If there’s soot on the bottom of the bowl, you may have to wipe some of it away to help the tape stick.
Apply Super Glue around the edge of the bowl and glue, upside down, to the iron candle warmer.
Glue rubber bugs to the base of the oil warmer. Hold in place with a clothespin until set.
