If you are using old candles, pour the boiling water into the old containers and leave to cool.

Remove the wax floating on the top.

Use dishwashing liquid and hot water to clean up any excess wax or soot.

Dry the glass containers.

Cut small pieces of sticky tape and fold to make double-sided tape then place in the middle of the bottom of each jar.

Cut the wicks so that about 4cm comes out the top of the jar.

Use a skewer to press them into the sticky tape so they stick to the bottom.

Place a skewer over the top and wrap the wick to hold it up in the middle.

Measure out the soy wax flakes (you will need double the amount - eg if your candle is 1 cup capacity, you will need 2 cups of soy wax flakes).

Place the flakes in a heat-proof jug and microwave for 1 minutes.

Remove and stir then microwave for 1 minute again then stir.

If there are still solid flakes, microwave for 20 seconds at a time until dissolved.

Add the fragrance oil, stir and then pour the wax into the jars.

Make sure the the wicks are in the centre then leave the wax to set for 12 hours.

Trim the wicks to 1 inch.
