Equipment:
Wax
Wicking - old cotton string
An old pot or pan - this will serve as the the bottom of the double boiler.
A large can - any type of old can will do.
Newpaper and/or Wax paper - and lot's of it.
An old pen - used to suspend the wick
A mold.
Method
Don't put wax in the pot directly over the burner. When setting up the double boiler, ensure that the water lever is low enough so the weight of the can and wax will keep it from floating around. Put the wax in the can and WATCH IT!!! While it is melting, cut a generous amount of wick and dip it into the melted wax several times,, allowing it to dry in between. By predipping, you will be able to form the wick into a straight line.
Keep adding water to the boiler. Don't let it boil away.
Wrap the wick around the pen, and adjust it's length in the empty mold, then set it aside.When the wax has melted, use a potholder, and pour it into the mold. Hold the mold at an angle and pour the wax down the side. Save some of the melted wax. You will need it later.
Set the wick into the mold ensuring it is exactly in the middle. Room temperature is fine, so is the refridgerator, the Freezer is a no-no.
Wax Contracts when it Cools.
After about an hour (less if in the refer) reheat the left over wax. You will need to poke several holes areound the wick, about half the depth of the candle. POur the wax up to the original fill line. This process may have to be repeated several times.
Molds.
Let you'r imagination run wild!! The basics include frozen orange juice concentrate containers, milk cartons, sand, chinese food containers etc. Try using an old toilet roll middle. They provide an intersting finish to you'r candles. Remember however to tape up the bottom VERY WELL, or else it will leak very badly. Don't use old soup cand as the are rippled on the edges, and tend to grip the wax.
