Try embedding herbs or spices in the pliable wax before you roll it up. Ice Candles Lacy, intricate ice candles are full of holes where the ice melted as you pour the hot wax into the mould. Wick the candle before pouring, but use a wick that you have entirely coated in melted wax, otherwise it will get wet and never dry out, you will have a hard time burning the candle. This will form a nice core for a hole-y candle, and will burn well. You can try making the candle with different sized ice cubes.
Small ones leave small holes, etc.
Fill the mould with ice cubes, then pour the melted paraffin over these. Let it harden then pour out the water. Tear away your mould and enjoy your new candle. Remove the seeds and innards. Use this hollow squash for a candle mould.
