When I do the bag shuffle (switch from my day-to-day work purse to an evening one, or a weekend one) I often forget my keys in one and off to work I go, only to discover I'm locked out when I return. The Doorganizer hangs from your doorknob and is bright red so it'd tough to miss (unless your decor is red, in which case it's also available in black or camel. It's got pockets for all those things we tend to misplace - iPods, keys, sunglasses - and those things we tend to forget - mail, grocery lists.

Also handy if you've got a husband/mother/father/nanny/brother/dogsitter/sister/babysitter/girlfriend/grandma/grandpa/wife/roommate/boyfriend/ houseguest who is always disorganized!
