Recycling your old candles

Do you like lighting candles in winter? You can do so and be ecological at the same time, by reheating in an old saucepan all your old bits of candles.
Pour it in a glass pot, in which you've put a stick (chinese stick for example) tied to some wick which will then stay in the middle.
Let it cool down.
You can also have fun mixing in different colours, just remember to always be careful to not burn yourself and always watch over your children.
