There is an art to candle burning! There is more to candle burning than lighting a wick and letting it burn........... A VERY important part of candle burning is wick trimming! Perfect candle burning is influenced not only by how a candle is made, but how it is burned. Trim your candle wicks! By trimming your wicks, you will have less soot and the burn time of the candle will increase. The perfect trim is 1/4". This is an important step when lighting your candle for the first time, and for each subsequent candle lighting. Some candle users will use scissors or nail clippers to trim their wicks. But, personally, a wick trimmer is my favorite tool! This wick trimmer is made to sit on top the cooled wax at 1/4". Used like a pair of scissors, you will get a perfect 1/4" wick trim every time!
