The methods are fantastic and easy to do!
I would suggest to perform the "in hand" version first
followed
by table top method as the latter is stronger of the two divinations.
I
showed this to a fellow magician in the order mentioned above. I used his newly opened deck and he's
responds was,
"Ok, you used my deck... can you see through the scarf?"
I've used
scarves, kerchiefs, bar and regular napkins.
Everything can be borrowed and can be presented
impromptu.
This is definitely a gem for bar/restaurant workers.
