Brevity has always been one of my challenges,
(as typified by how my posts often resemble epic-novels here...LOL!)...and so "traveling light" isn't something that comes naturally, which is why my purse usually looks more like a huge survival backpack than a purse. ;D
But...Anakin cannot carry a purse to an event, not even one of those "man-purses" like on Seinfeld, ;D but, unfortunately those little pouches do not hold much, SO, the night before a costume event I have to literally
force myself
(no pun intended) to have what I call "Pouch Casting Auditions".......a painstaking process in which I select which objects will make the final cut to go into the pouches and which objects will have to stay home.
The process usually takes me forever, because I always want to carry everything under the suns, juuust in case I might need it. I'm like a psycho-girl-scout who takes the motto "always be prepared" to absurd levels......
"you know, I better take this small tub of Oxy-Clean with me just in case I spill something on the costume 'cause jeez you just never know....." 
;D
That worry-wart software glitch in my mainframe, coupled with the necessity to adhere to the finite carrying-capacity of those two small pouches, has been the mother of some fairly clever and often humorous invention when it comes to pouch contents.
Here are some excerpts, in hopes they might be of some amusement
(or perchance even some assistance?) to those other brevity-challenged Jedis out there who are attending Dragon-Con this weekend......
1. Small flat leather folding business card case with driver's license and I.D., (for those occasions when the basic
"you-don't-need-to-see-our-identification" Jedi mind trick will not work on event staff)
also inside the case will fit credit/debit card, cash, parking ticketstub, business cards, and of course, the AAA Auto Club Card, in case I happen to lock my keys in my car
(another commonly-occurring brain software glitch). Along with those items, I tuck a small single-dose envelope of BC headache powder in the business-card folder, which fits nicely and does not take up the space that Aleve or Tylenol tablets would, and in the hot summer I also tuck one small packet of "Emergen-C" Vitamin electrolyte powdered drink mix in there too, so I can toss it into a bottle of water and quickly replenish what the heat and sweat have taken out of me.
(...so, do I sound like a psycho-girl-scout yet?? Oh, just wait - it gets better. Be afraid...be very afraid... ;D)2. a very small digital camera. I was lucky enough to be given a Contax 4R as a gift a few years ago, and it's the smallest coolest digital camera I've ever seen, about 1.5" wide by 3" long. It fits easily in one side of the taller pouch quite well and leaves room for other things, like.....
3. my cell phone, which is a RAZR and therefore is thin enough to not take up too much room. Also, an extra photo memory-card.
4. The world's smallest "travel toiletry kit.....a small 2" square, flat leather envelope-pouch which encases a few "brush-pick" toothpicks in it, a small flat container of Listerine Breath Strips, and a tiny flat round metal tin that once held trial-size lip-balm but now has been packed with a small bit of "emergency antiperspirant/deodorant" which can be dabbed on with fingertips.
(hey, it's strong enough for a man, but made for a woman....LOL!)
5. The world's smallest solution to
"How To Maintain Anakin's Wet-Hair ROTS Look Without Having To Carry A Bulky Bottle of Hair Gel"..........
(and this is brilliant, but in an almost-psycho way).......an empty Visine bottle which has been rinsed out and de-labeled, then filled carefully with Frizz-Ease Hair Serum, enough for several applications during a day. NICE!!! ;D
6. "Emergency Cyber-Glove Repair Kit"....
(because rubber gasket material flatly refuses to stay glued to leather in hot weather).......one small bottle of Heavy Duty Super-Glue Gel, and 3 black rubber bands wrapped around the Super Glue bottle. What are the rubber bands for?...to hold the rubber gasket material in place around the glove while the glue sets. Otherwise, trying to hold them all three in place at the same time with only two hands makes me crazier than even Anakin could get away with being. ;D
7. Extra AA batteries for light saber, and a small eyeglass-repair screwdriver which opens battery casing on saber,.......all of which fit neatly into
what?.....
(and this is the really funny part)...one side of a pink plastic tubular purse-container which is actually supposed to enclose, well, two of those oblong feminine products that we all know and love. What fits neatly into the other side needs no explanation.
;D
(...hey, Anakin,...ha, ha,...what's in the bright pink tube?...)
(...not funny, Master. I'm just carrying them for Padme.) ;D ;D ;D.....moving right along........
8. Emergency Makeup Kit,...a tiny tube of latex form-glue and a red pigment pencil to make sure scar makeup on the right forehead stays intact. Plus, a tiny bottle of Spirit-Gum Adhesive,....because nothing causes more of a disturbance in the Force than when a prosthetic sideburn comes unglued in the wind, or a prosthetic eyebrow falls down into your mouth while you're speaking to someone at a convention.
9. Last but not least....instead of a bulky set of keys on a keychain, I use one of those tiny little rectangular "Runner's Key Holders" with just my two car keys in it. It's made to velcro-fasten to the laces of a jogging shoe, but will also velcro nicely to the inside wall of one of the pouches. This saves space, AND cuts down dramatically on the afore-mentioned reoccurring tendency to lock my keys in my car.
(because, hey, ...we Chosen Ones cannot be bothered with small insignificant things like using one's Short Term Memory. LOL!!!)
......... ;D
Have a great weekend, all!!
