Today I am going to add orange candles to the list of DIY candles. The advantage an orange candle has over others, is that it has a built in wick, so no additional wick is required. This literally means that if you have an orange and some cooking oil, such as plain vegetable oil or olive oil, you have potentially got two candles (because you cut the orange in half and use both halves as candles).
Another added benefit is that candles made from oranges, smell amazing!
It is pretty straight forward, but if you want more details, check out the tutorial below from Instructables.
