To keep the candles of WoodWick burn well for as long as possible, it is a good idea to let the candle burn for at least an hour each time you light it. This way, the candle will "swim": the wax melts to the edge. This causes the candle to harden evenly and you won't get burn-ins. This way, the candle will burn well again and again and you will enjoy the fragrance for a long time!
