trim your candle wick
to 1/4" in between burns using a wick trimmer or nail clippers to ensure a healthy candle! a long wick makes a larger flame which means burning through your wax + fragrance faster.
wick won't stay lit?
try melting a bit of the wax closest to the wick with a match or a lighter, then dab the melted wax to give your wick some breathing room!
