I just use my pockets. I perform magic for a living and don't want to arrive/perform looking like a doctor.
I think it's best to use pockets, but NOT to fatten them out. You still need to look 'slim', so - slim props are best.
Also, when I work - I HAVE to carry my car/house keys, money, contract (for gig) etc... There never is anywhere to leave it/them!
1) Playing Cards - easy
2) Kaps Wallet - easy
3) Rope - hang from belt
4) Cups & Balls - use wine glasses! (As a friend does...YES, clear glass!)
5) Handkerchief effects - use napkins
6) Packet Tricks - easy
7) Scissors (for point 3) - in mobile/cell phone jacket pouch. NOTE: I use ROUNDED end MINI scissors
EASY to do 2 hours with NO case!
Anyway, 90% of my work is done with a deck of cards, my diary trick (flat), my "always different card" version of magician's policy (flat) and a few packet tricks I do.
I NEVER do effects that can cause CLAIMS. I NEVER do tricks with finger rings (I know a magician who got stuffed by a client denying ring in wallet was hers), fire or card to ceiling. Yet again, a magician in UK did card to ceiling...hit expensive cornice...it fell and smashed onto a grand piano! THEN, a chip of wood hit a client! BAD NEWS! Funny NOW - but not then!
Anyway....just a few thoughts!
