Every year, as the weather turns colder, I find myself lighting candles more often: with a coffee, a book or an evening of doing very little. I also notice that a candle can burn differently in winter than in summer.
Candles benefit from a steady room temperature and a position away from draughts. In a cooler room, wax takes longer to warm up and melt. The flame may initially be smaller and the fragrance develop more gradually.
That can be quite normal.
Position matters too. A windowsill may look lovely in a photograph, but cold glass and moving air can affect the burn. Choose a stable surface away from windows, draughts and direct heat from a radiator.

If you bring a candle indoors from freezing temperatures, let it reach room temperature before lighting it. A large temperature change can put stress on a glass container. Give it time rather than rushing.
Then light your candle, settle in and enjoy its fragrance.
