Dunno if this one's "original", but I formed this spread when I was having a few problems. This spread can be used for problems between 2 people, friendship or romantic relationships or otherwise.
It's supposed to be in the shape of a question mark!
1 = core of matter
2= what you think is the root of the problem
3= what he/she thinks is the root of the problem
4= what you have actually overlooked/need to be aware of
5=what is the real root of the problem
6 = the key/advice
You can also pick out a 7th card for "clarification".
I;ve used this spread many times in private readings for friends and it works fine. Do give me some feedback.
