This is a very simple and easy spell that does not require a lot of difficult to find ingredients. It works through the power of your intent.
Take a cord, of the appropriate color (see the correspondence tables for colour correspondences), and shape it on the altar into a rune or the design of the object you need: a car, a house, a paycheque or whatever you desire.
While you do this visualize the needed object; raise power and send it forth to bring it to manifestation.
So mote it be.
