I carry with me all the Time:

3 Sponge Balls
Rubberbands
2 Coins
Fire Wallet (It's also my regular Wallet)
Business Cards
Deck of Cards for my Haunted Deck
Tiny Plunger
TT for Bill Switch
Sometimes 2 small Slydini Silks

That's it. fits perfectly in my Waste Pockets

......Haha! I'm sure you can!

Deck of cards with a dupe and a Sharpie in my right pocket
Pack of smokes with a lighter ready to go for warning! and a certain other card revelation trick (trying to avoid exposure) in my left pocket
F1 nitro wallet (as my daily wallet) with Extreme Burn, Powerball, business cards, loops, Lubor lens, warning refills and some extra cards
Pro flite keychain with keymaster on it
It sounds like a lot but in the end its just a pack of cigarettes, a wallet, and a keychain. The only strange things are the cards and the sharpie.

Sponge balls and a thumb tip.

My Heirloom Wallet is my everyday wallet. In it I have Powerball 60, The Gift by Derrek Lau (which I love), one of the "outs" for Knock'em Dead, No Diary Diary and a few receipts for Burn Notice. What a mouth full. Aside from what I have in my wallet I also carry a deck, rubber bands, Linkey on my keychain (Awesome By The Way), my everyday ring and some velvet string. That's when I'm not carrying my messenger bag.

Nothing. If they want to see something spur of the moment then they can provide the materials.

I've since added Ian Garrison's Dances With Ropes for my daily carry.

I keep two thin rubberbands on my wrist at all times adn I can perform CMH

Nothing!

Assertive Possitive Negative by Scott F Guinn.
Only need a b-card or small piece of paper and pen and your spectators imagination.

I always carry set of color changing knives and a stack of 4 thimbles.

A large paper clip in my Real Man's Wallet ,a hen & chicks, an elastic loop around my finger, sometimes, rubber bands around my wrist.

Three sponge balls, a deck of cards, a magic wand, six half dollars, a sharpie, business cards and a hat.

I think the best way to be prepared is to have a few things in my wallet and on my keychain. In my wallet I usually have a few rubber bands, a gaffed bill, and one or more coins. On my keychain I have a piece of string that is tied in the "survival" string tie way. I also have a gaffed key ring sort of like a mini linking rings. There are a bunch of other things that can go in and out of the wallet or key chain.

To me, these are more "natural" ways to carry magic. By "natural", I mean that I don't have to be thinking "magic" when I get dressed. I would love to have a very "natural" way to carry a tt. I think that would be the perfect addition. Unfortunately, I don't have a tt that fits in my wallet or on my keychain. Maybe someone will come up with a collapsible tt.

You don't want to think 'magic' when you get dressed?
I'm not following.

The natural way to carry a TT is on your thumb!

I keep mine in the little pocket within my jeans pocket (match compartment?). It's perfect for quickly putting on as it keeps it facing the right way.

Amen, David.

What I mean is if I am not planning on doing magic, I just want to put my wallet and my keys in my pocket and I'm out the door. I don't want to have to think about what magic effect I am going to put in my pocket. If I have a few things in my wallet or on my keychain, or have a few impromptu things I can do with regular items like borrowed coins or pieces of tissue, I'm always ready to go.

Lately, I am really into gift magic. if someone asks to see something, I really like to leave them with a gift. For that reason, I carry a few things in my wallet and something on my keychain that I can give away. On my keychain, I carry a woven piece of string with a couple hand-carved fish beads. I do some magic with it and give it away as a bracelet.

Gift magic is why I would really like to carry a tt. tts are great for gift magic. Maybe I should get in the habit of putting the tt on my thumb and then placing it in the change compartment of my pants pocket.

Thanks for that idea David.

I like carrying a TT, at least two rubber bands, a coin and the Hotrod stick as I am around children quite a bit and they love the color change.
