Here’s a great money-saving tip to fill your room with your favourite scent: spray perfume or aromatic oil on a rag than wipe it on a cold incandescent light bulb.
Whenever you turn it on the perfume will heat up and fill the room.
Just make sure to do this before the bulb gets hot - if you don’t, it might break or explode. I love Calvin Klein Euphoria but I prefer to smell it without glass in my eyes!
