Candles

I'd use white or blue, or even purple, and then maybe carve the person's name and Aquarius' sign - http://0.tqn.com/d/astrology/1/0/Q/-/-/-/Aquarius.gif - in it. And maybe using a green candle could help too, hopefully the spell calls for it! Since it is job spell, green candles could be used for wealth and prosperity. I'd carve rune symbols such as Feoh in it. Hope this all helps! :D
