I was wondering if people could teach me how to fan cards between my hands and in one hands, and also how to spread cards on a table.
These moves are more difficult than they look. You have to practice them before they actually look nice. By "practice" I mean something like 10-20 minutes a day for several weeks.
You should also get some book or DVD on the subject - there have been some recommendations in this forum already. Actually, books are cheaper but they won't tell you how a specific move looks. They also may not tell you how to turn a collection of moves into a routine that impresses an audience. That's the advantage of DVDs - of
good DVDs, of course ...
Judging from your signature line I guess that you already have the book from Bill Tarr? It does contain detailed descriptions of spreads and fans and it should be enough to get you started.
Just start with a new deck and use a surface with a good "grip". A magician's close-up mat is optimal, but a wooly tablecloth is fine as well. I found the bed to be a good place to practice springing the cards, BTW
Besides, knowing card work is by no means mandatory if you want to call yourself a "magician". There are famous people who never touch cards, although most people do know at least one basic routine. Just a thought: A single coin vanish and production move is much more versatile and can be done totally "impromptu" as opposed to card routines. Add these moves to your daily practice schedule (should only take 5-10 minutes extra) and you may find it a very good and gratifying investment.
