Okay, folks, my incredibly artistic, but not computer savvy sister has decided to add candle making to her repertoire. She wants to copy an old pillar candle (probably 50 years, at least). which is decorated. While I have no doubt she can do it, finding a 4" mold that is 18-20" long is the trick. My DH said "What about PVC pipe?", which is how I got here. Cutting it lengthwise and using radiator clamps is brilliant. Wiping (rather than spraying) Pam is also great. But, two things are problematic: 1) what does one use as a "stopper" for the bottom? (I assume drilling a hole in it, feeding the spooled candle wick through it, and preumably knotting the end would be the thing to do), and 2) There is an oval cut-out midway up the candle she has (the old one). I get that the wick obviously cannot go the length of the candle, so are there any ideas? I'm thinking a votive-sized cut in. But I'm a whiz at over-engineering, and completely non-talented in any artistic endeavor (we joke that, when talents were handed out in Heaven, Chrissy stood in that line twice - once for herself, and once for me. I mean, she doesn't even use patterns when sewing, for Pete's sake!)) . Please help.
