How-do, Gang.

Just came across an interesting technique for decorating candles, specifically larger pillar candles, even the wax coated ones with LED bulbs, so figured I'd describe it here.
I plan on making a few of these in the next few weeks, we'll see how it goes.

I'm wanting some pillar candles with ghost faces on them, so here is the plan-
Using a small paring knife, a sharp edged spoon, a wax carving tool, what have you, scrap out the mouth and the eyes on the side of a white pillar candle. Not too deep, in fact less than a 16th of an inch, and make sure you leave the carved areas rough and textured.

You aren't actually carving any depth at all, more like scraping a rough texture into areas to be painted.

Next, pop a Black unwrapped crayola crayon into a scented wax/oil burner, the sort with a tealight for warmth under the dish. I suppose you could also use a warming plate and an old metal muffin tin, just keep the heat on a low setting for safety.

When the crayon has melted, use a cheap nylon brush and carefully paint the melted wax into the carved areas of the candle. You'll want to have the candle on its side, and let each layer of painted wax set up a little before rotating the candle to paint more. The rough texture of the carved areas should hold the melted crayon in place better, and the melted wax will be much smoother as it cools.

Once you have painted black wax into the eyes and mouth, turn the heat off of the crayon and let it cool. You should be able to pop the cooled wax cake out in an hour or two. By this time, you should (in theory) have a white ghost candle, with a pair of black eyes and a wailing or laughing mouth.

As the candle melts, the painted features will be just so much wax - though you may end up with dark tears streaming from the eyes before they go.

Wax covered LED candles can be given the same treatment for those who would want a longer lasting prop.

I'm looking forward to trying this, but since the season is upon us, I wanted to share the concept before I give it a go.
I'd hate to have a really neat craft finished and posted on October 15th.
Better to give my fellow ghouls a head start.
