candle is melted, dip the anchor end of the wick (the one with the metal plate) in the melted wax and then quickly position it into your 4inch jar. the wax should melt and stick the wick down. if not, try again. you might also want to use a pen or something similar to tape the top of the wick to. this will prevent it from falling down once you pour the hot wax in.
when the first candle layer is all melted, take it out of the water using the tongs. pick out the old wick that was originally in the candle and throw it away. wait about 1 -2
