An old skill that was popular among candle makers was to attach the wick to the bottom of the candle using the wax itself. If you don’t have tabs, dip the end of the wick into the melted wax, then quickly transfer the wick from the wax to the jar.
Center it quickly, and press the end of the wick against the bottom of the jar. Just as the sprinkles were set against the side of the jar with the melted wax, you can do the same thing with the wick against the bottom of the jar.
After a few seconds, the wick will be secured in place, and you can pour the rest of the wax in when ready.Of course, glue and stickers work just fine, but if you want to embrace some of the candle making crafting skills at its roots, try this method next time you make your own candles.
