yes, yes you should be trimming your wicks! our wick trimmers are small (6.8" long) and lightweight, but powerful enough to handle cotton and wooden wicks.
how & when to trim: trim your wicks each time before lighting your candle. cotton wicks should be about 1/4" long (think straight up and down with no "mushroom" on the end) and wood wicks can be even shorter around 1/8" at an even length. don't trim while your candle is lit or while the wax is hot.
