For staging, too much small stuff is called clutter. When moving, misplacing the small stuff is another matter. Don’t spend time and energy sweating about the small stuff.
Of course, I hope that clients will take this in its larger symbolic meaning. But I also want them to take me literally, to round up all the small stuff, because really, so much of what we need day to day is really, really small. So, pack all real jewelry, passports, cell phone charger, extra car keys, extra contact lenses, checks, pending bills, prescription meds, etc. in one suitcase and carry it with you. Chances are they won’t get stolen, but, they might get buried in boxes, and once missing, you will obsess until they are found. Clients of mine recently found their extra set of keys in a butter dish. When they found them, after much searching, they, of course, remembered putting them there for safe keeping!
