With a wick holder, hold the wick at the center of the candle mold a few centimeters above the mold. Fill the candle mold by adding heated wax after it has just turned into liquid. Wait for some time, separate the wick holder and pull out the newly made candle from the candle mold.  You can mix fragrance oils or dyes after turning wax into liquid and before putting it into the candle mold.
