Candles not only give off a warm glow, but they can add fragrance to any room. Put those boring unscented candles to good use by adding essential oils. Scenting an unscented candle can be quick and easy.
As a safety precaution, do not add oils to the candle while the candle is burning.
Step 1:
Light the candle and allow it to burn until there is a pool of melted wax in the candle.
Step 2:
Blow out the candle and wait for the wick to stop smoking.
Step 3:
Add several drops of your favorite essential oil or a combination of essential oils.
Step 4:
Allow wax to cool.
The next time you light your candle, it will fill the room with beautiful fragrance! This process may need to be repeated as the scent diminishes.
