Used candles + wicks for craft (Hoddesdon EN11)

Various used up candles (little or no remaining wax) in glass candle jars, and set of 150 new wicks (3 different lengths) for a craft project.
We simply haven't got to this project, and thought it might be better suited to someone more crafty and practical than us!
The idea is to melt down the small amounts of remaining candle wax in the jars and in other used-up candles you may have (stand jars in hot/near boiling water), then place a wick in one large empty candle jar, and pour the melted wax into that, to create an unusual candle of mixed colours.
This can be repeated with other used candles you have - it's a recycling, low-waste option for used candles. You may be able to buy some additional craft candle wax to top up as needed.
