Let the candle burn till the melted wax reaches the edges of the jar each time to avoid any tunnelling (extra wax on the side of your candle).Burn the candle for no longer than 3-4 hours at a time to ensure even burn. Burn on heat-safe surface and area free of drafts.Discontinue use when 1/2 inch of wax remains to avoid jar from overheating.
Wood wicks take a few times to stay lit since your dealing with real wood, think of it like a bonfire.
Before lighting your candle make sure to trim the wick each time. You can also run your finger across the wick by slightly pressing it, extra chard will come off. Dump out the excess wick before lighting your candle.
Slightly tilt your candle and hold the flame to the side of the wick for few seconds and let the flame distribute evenly.
