Hi DrMojo!!
I read your profile so i know you are one expert at tarot. For readings for two months i use to do a linear spread. But i think that is very easy, but i will write that.
The name: the 7 cards
You put at the table 7 cards, than you put more 7 underneath the first 7.
Than the querent choose one card of the spread.
This will be the first, and you start to read for this first.
Imagine 7 cards on the table, the querent choose the 3, so it will be the first.
But my favorite linear Spread is the carpet
You can do it whith 21, 14 or 7 cards.
You put 7 linear cards, than if you whant you put 7 underneath the first, and more 7 underneath the second line. But you posted that you want a linear spread whith 7 or 13 cards so i will talk only whith 7 cards.
1- Family life
2- Work
3- Love
4- Friends
5- Money
6- Health
7- Spiritual
I do this spread a lot, and i had a wonderfull readings whith this one.
Actuatly, i have only one spread that for me works better.
I hope you like it.
