I've used candles in several of my assemblage pieces, because I love how they are a can't fail metaphor for being consumed by passion, being burned, feeling the heat. Aside from the nifty metaphor aspect, candles are just plain fun to play with. Yes it's the same thrill that playing with matches has. This morning I was working on creating the center piece for a new assemblage...a doll standing in a glass container surrounded by candles burnt to varying heights and heavily dripped. I somehow managed to do this without burning myself OR setting off the fire alarms. I'll post pics of the finished piece when I get there.
