You will need:
length of wick
Wick sustainer or Blu tac
2 saucepans - one that fit inside the other
candle dye (optional)
Essential oil / candle scent (optional)
Most of the items such as wax pellets and wick sustainers, wick etc can be found in most good craft shops.
Fill the larger pan with about 1/4 full of water and bring to the boil.
Put the wax pellets into the smaller pan and gently heat on top of the larger pan, making sure the smaller pan doesn't touch the water in the larger pan.
Add a few drops of essential oil or candle scent to the wax if desired.
Add candle dye to the wax at this point if you want a colourful candle.
When the wax pellets have melted take the pan off and dip the wick into the melted wax briefly and then remove.
Using the wick attach to the wick sustainer (or a small amount of Blu Ta) and stick to the bottom of the tea cup. Holding the length of wick up tie it around the middle of a pencil and rest the pencil across the teacup. You can cellotape the top of the wick if you like to keep it in place.
Reheat the wax if necessary otherwise pour into the teacup saving some wax in the pan to top up the tea cup later. Leave to set .
When the teacup has set there might be a dip in the middle, the leftover wax can be reheated and used to fill over the hole so that the candle is flat on top.
Unravel the wick from the pencil and using scissors trim the wick a few centimeters above the top of the candle.
There you have it, a lovely tea cup candle!
