YOU WILL NEED:
Candle wax (or leftover bits from old candles)
Wicks (try hobbycraft.co.uk)
1 Clean the eggshells in soapy water and leave to dry on kitchen towel.
2 Heat the candle wax in an old pan over a low heat until it melts. Take off the heat as soon as it has melted.
3 Place eggshells into the carton and then carefully pour liquid wax into the shells.
4 As soon as the wax starts to solidify, stick a piece of wick of about 10cm length into the centre of each eggshell, so that it reaches the bottom.
5 Leave to harden, occasionally encouraging the wick into the centre. The wax should take a couple of hours to harden completely.
