Just thought I would add my contribution here. When I give a reading, I usually begin with a Celtic Cross for an overview of the querents general life situation, then I progress to what I call the Fifteen Card Spread. I am not sure if this is someone else's creation!! (ha!), but it works for me.
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
The querent is asked of a specific situation for which he or she would like further insight. Five cards are then picked and overturned. To provide further insight, another five cards are then picked, and so on. It is important to select and read only five cards at a time, leaving the selection of the next five cards, till after the first five cards have been interpreted. Hope that makes sense.
I find a connection with this spread. And it has rarely shown me any untruths.
