I love to burn candles every evening but they have been getting so expensive I needed to find a way to make them burn longer. I bought one of those 3 wick candles, that they have at the Dollar Store. I would only light one of the wicks instead of all 3. Each night I would light the wick next to the previously burned one and so on, to keep the candle burning evenly.
Believe it or not, I managed to burn that one candle for almost 3 weeks nightly and one wick burning smelled as good as if all 3 were lit.
