scented candles, aromatherapy oil/ essential oil, or liquid potpourri.
I use candles in my room, I have like 15 candles no lie, though some are for decoration and not burning. Yankee Candle has awesome scents and I also use the candles that float in water, its safer!! I also use oils to from Bath & Body Works or Wallflowers from there also, they work amazing, you can smell them so good!!!
candles because i dont really know what the other things are.
Definitely candles, I love the flickering flame.
I like candles, plus they look really pretty.
