I always have candles on the go and love a really rich Christmassy smell. More spices/Oudh kind of smell than anything sweet. Two Christmas candles I’ve bought so far smell of absolutely nothing! (Sainsbury’s & H&M)
We do have more expensive ones but I like them burning pretty constantly throughout the winter so looking for an economical alternative.
I also read about putting drops of oil into your radiators which wafts the smell about when they’re on but I’m not sure if that’s recommended 
Any great ideas?
