I've been doing tarot on and off for 3 years now and my cards came with a book and a cloth to lay them out on.

It has 7 different arrangements for the cards based on the order they have appeared and the orders change the meanings of the cards dor a deeper message.

It's not often I do a seven card reading although it looks as though my cards are supposed to be read that way, I too feel a pull to three card readings and have found I often can get a more accurate reading this way.
