A silver candle and a gold candle
A small cloth pouch with a drawstring
A handful of play money (like Monopoly) of different denominations
A taglock for yourself (hair, nail clippings, etc)
Ginger (for power and success)
Nutmeg (for prosperity)
Prepare your workspace as you normally do - if you invoke deity or call the quarters, go ahead. Light the two silver candles on either side of your space, so that you are working between them. As you light them say: "Gold and silver, silver and gold, make money come and dollars unfold."
Place your play money and the taglock into the bag. As you do this, think about yourself and the money being together. You might even rub the taglock and the money against each other as you place them in there. Say "Cast from necessity, not from greed, all I'm asking is for what I need." (Obviously this might not be the spell to use if you're trying to win the Powerball.)
Place the ginger and the nutmeg in the bag, and picture success and prosperity coming your way. Hold the bag in your hands and say, "Tens and twenties, fives and ones, as I will, it shall be done."
Take a moment to think about what you will do with the money that comes your way. Will you use it to get out debt? Pay a bill? Have a little bit of extra grocery money? Allow the candles to burn out on their own. Place the bag in a safe place where it will be undisturbed, and out of sight. Results from this one seem to come in very odd ways, but so far it has worked every time for me.
