I just got a mold for doing 6" taper candles, but I used to do all my candlemaking as "dip" style tapers.
Dip style is best done in winter when it is cold outside. You start with a long piece of candlewick. You dip it in wax and pull it out. A little wax will harden on it. Dip again and again until it is almost as big around as a pencil. Now you have to roll the squiggley thing straight on a flat table top. Easy peasy, you are on your way. Dip and wait for it to harden. Repeat until the candle is as thick and long as you require. If you dip too many times in a row the candle will actually heat up and begin to melt, getting thinner and thinner.
Thats why it is so nice to do on a winter day....outside. Dip a few times to build up and then hang the candle while you work on the next one. The colder it is, the faster the wax will build up with each dip.
ALWAYS make sure that the wax is melting in a double boiler. NEVER heat wax directly in the pan over heat...if it gets too hot, it will flash over and you will have fire. In this case, FIRE BAD! For a barbecue grill, fireplace, or ring of stones at a camp then it is FIRE GOOD! But a big old pan of blazing candlewax is not good. The copious black smoke burns the eyes and makes wifey mad.
I don't have a wifey anymore.
But I still make candles.
