Step 1. Prepare the pebbles
Prepare the pebbles by adding a small amount of water. Mix around with your hands to make sure all pebbles are damp. This trick helps the pebbles hold their shape. If you find you've poured in too much water, just drain the pebbles and then use.

Step 2. Make the mold
Flatten the surface of the pebbles. Then using two hands, press the object you're using to shape your candle into the bowl of pebbles to make the mold. Slowly pull out the object once you are happy with the shape or the depth you pushed it in.

Step 3. Prepare the wax
Now prepare the wax. Melt all your bits of wax in a pot. Keep stirring on a medium heat as the wax melts. Never leave it unattended while melting. Make sure as you are doing this, you safely remove all wicks from the old candles you are melting. For example, pull them out with tongs. Once all the wax is melted, put in your cooking thermometer and heat the wax to a temperature of 275 degrees Fahrenheit or 135 degrees Celsius. Note that this heat is a bit hotter than is usually recommended for making other candles.

Step 4. Prepare the wick
Prepare the wick by dipping a piece of wick into the hot melted wax and then lay it out straight on a piece of paper. Allow to set.
