You will need:
Commercial wicks (string can be used)
Old candles -- melted down
Old crayons for color
Scents and wax colors can be purchased
Molds - or containers
Beeswax can be cut with a knife if the knife is warmed first. Wrap desired amount around wicks to form long tapers or cone shaped candles.
To melt the paraffin you'll need a double boiler and be real careful about how hot you get it as it is volatile. Old candles can be melted down in the same manner and crayon pieces added for desired color.
Yogurt or butter tubs will make good molds for your candles or pour melted wax over crushed ice in a square milk carton and add glitter - wow! Or you can dip the wicks repeatedly into melted wax in double boiler and let harden between dippings for tapers.
