While it’s not absolutely impossible that I made a mistake, it is highly improbable because I'm a perfectionist. The more likely scenario is that you have placed your candle in a room that is too big, and the candle simply isn’t strong enough to permeate the space.  Some scents are also stronger than others, for instance our Spiced Pumpkin candle has much deeper notes than our Big Sister candle which is more fresh.  This can also affect the scent throw.
