I have devo's XB DVDs and the trilogy for dan and dave but i still cant get how it is done , where else can i learn it or what is a common mistake that people make while trying to do it?
theory11 — Magic Tricks & the World's Finest Playing Cards
as if you did not learn it from XB
it like spells out what the common mistakes are
1. DECK CONDITION
2. GRIP
keep trying it will take at least a month, maybe three before you can really do a fully formed fan nicely.
