Always trim wick 1/4 inch before use. To best use your candle burn first couple of hours to create a full melt pool of the candle. Candles have memory therefore if burned for a couple hours your candle will pick up where it left off at. So if your candle is 3" in diameter, then you will let it burn for 3 hrs. If your candle is 4" in diameter then you should let it burn for 4 hrs. So remember for every inch of your candles diameter its best to allow it to burn for one hour of each diameter size for the burn time. You want to get the best results of your candles melt pool and fragrance scent. Never leave a burning candle unattended. Burn within eye sight. Keep away from things that can catch fire. Keep away from children and pets.
