Make Your Own Lemon Candle in a few easy steps. All you’ll need is a lemon, a knife, some olive oil and something to light your freaky clean candle. 1. Cut lemon in half. 2. Scoop out inside of both halves and leave the rind to form a wick in the middle of one of the halves. 3. Slice off the top of one half. 4. Use a cap’s worth of olive oil to coat the rind wick. 5. Light the wick and place the top back on.6. Enjoy a lemon-fresh scent. Because when life gives you lemons, make lemon candles.
