Lightly spray your mold with Mold Release. (Photo 1)
Use a wicking needle to thread the wick through the hole in the bottom of the mold. Pull the wick so that it is about 6” (15.24 cm) longer than the top of the mold. Leave the wick at the bottom of the mold long, that way when you remove the candle, the mold will rewick itself! (Photo 2)
Most molds have at least one cut in the side. Take the time to make sure that the seam(s) are aligned properly. This process will alleviate the need to repair a bad seam on your candle. (Photo 3)
Use the rubberbands included with your mold to secure the seams in place, readjusting if necessary after the rubberbands are in place. (Photo 4)
Secure your wick over the mold. Bobby pins or popsicle sticks work great for this purpose. You want the wick centered and straight but not too tight. A wick that is too tight or too loose will effect the way your candle burns. Pour your melted wax into the mold slowly. (Photo 5)
The slower your candle cools the better it will turn out. Once your candle is completely cooled, remove the rubberbands and pull the seam(s) apart. Remove the candle from the mold and trim the wick at the top and bottom of the candle. (Photo 6) Your mold is now wicked and ready for your next pouring. The bottom of the candle is likely to be uneven. Use a metal pie tin on the stove to gently warm the bottom of the candle and flatten it out so the candle will sit level. Congratulations, you are now a candlemaker!
