Valentines Day is primarily associated with a romantic setting. So candle will be the most successful gift.
Candles impart an atmosphere of sensuality and set up the romantic mood. In the candlelight, in the dim light, everything seems so mysterious and inviting.
In order to make the interior of a passionate and mysterious, you should use a large number of small candles. For a romantic dinner, small scented candles (such as strawberry or rose) can be arranged on the floor, that they create a sense of white clouds.
