Wicks come in flat-braided, square-braided, and cored styles and in a range of sizes. Choosing the right wick for the candle you are making is important; it will have considerable impact on the success of your candle. Suppliers of wick material usually classify candles by diameter. The larger the diameter of the candle, the larger the wick you will need. Square-braided wicks are the best choice for beeswax candles, pillars, and blocks.
