You need an electric candle mold. They come in many shapes and sizes. I make mine, but also have purchased them from Ginger at Flexible Molds. After the wax sets up, all you need to do is place a 6 foot plug and socket cord, up into the middle of the wax shell. Screw in your light bulb, 7 watt silicone tipped bulb for the grubby look, and plug it in. I take soy wax and make the tops look like frosting by whipping and glazing the candle. I also embelish with wax embeds for different looks. I use a pillar or embed or hurricane wax. Container wax is too hard to get out of the mold. The idea behind this candle is that the 7 watt bulb warms the wax just enough to let out a subtle fragrance. You have the warm glow of the candle, and gentle smell of the wax, but no open flame. My kids have them in their bed rooms as night lights. I just love them. They look complicated but are SO EASY to make. Let me know if you are interested in more detailed instructions. I can send them to you via email. I also have a ton more pictures. Pumpkins, snowman faces, grubby loafs, cakes, and more.
