The Tarot layout known as the Celtic Cross is one of the most detailed and complex spreads used. It's a good one to use when you have a specific question that needs to be answered, because it takes you, step by step, through all the different aspects of the situation. Basically, it deals with one issue at a time, and by the end of the reading, when you reach that final card, you should have gotten through all the many facets of the problem at hand.
Lay the cards out following the number sequence in the picture. You can either place them face down, and turn them as you go, or you can place them all facing up from the beginning.
Note: In some schools of Tarot, Card 3 is placed to the immediate right of Card 1 and Card 2, in the place where Card 6 is displayed on this diagram. You can try different placements and see which works best for you.
Card 1: The Querent
This card indicates the person in question. While it's typically the person being read for, sometimes messages come through that refer to someone in the Querent's life. If the person being read for doesn't think this card's meanings apply to them, it's possible that it may be a loved one, or someone who is close to them professionally.
