This is just too fabulous an idea -- and it's pretty, too! Jimmy Pickles makes these wristlet keychains in tons of colors and patterns. They fit on your wrist and have a large ring for all your keys. This is perfect for me, because it feels like I'm constantly jumping in and out of my car, and I keep forgetting if my keys are in my pocket, in my purse, or (yikes, too late!) on the front seat as I slam the door shut.
