Our specialty, core-less cotton, paper and beeswax wicks are "self-trimming", in that they curl slightly as they burn. This aids in burning off the end of the wick as it goes so there's less left to trim after each burning. On occasion, you may notice "mushrooming" at the end of your wick. This is simply carbon buildup and is typical of core-less/lead free wicks. To quickly and neatly trim your wick, we recommend turning your cooled and hardened candle upside over a garbage bin where you may simply trim or pinch the excess wick to 1/4 of an inch. Prior to relighting, make sure you clean away any soot or debris from the candle surface.
