If you used a wick pin, gently insert your wick, and do the same.
Be sure to burn the candle at least one hour for each inch of its diameter the first time you burn it. Take notes on how it behaves, how big the melt pool becomes (and how quickly.)
As the pillar burns down (assuming it's burning well), you can "hug" the candle, that is, gently press the outside rim of the candle in a bit so that the top rim melts and the candle burns evenly all the way down.
