Rewicking a candle is the process of replacing the wick in a candle once it has burned down to a certain level. This is important to do in order to keep the candle burning evenly and to prevent it from tunneling, which can occur when the wick is too short and the wax around it melts faster than the wick can burn.
There are a few different ways to rewick a candle, but the most common method is to use a pair of tweezers to remove the old wick and then insert a new one in its place. It is important to make sure that the new wick is the same size as the old one, and that it is centered in the candle. Once the new wick is in place, you can light the candle and enjoy it as usual.
