If you're the kind of person who often walks out of the apartment without your key (um, yeah, I am totally one of those people!) here's a quick little DIY to keep your keys where you're likely to see them … on the light switch!
There's a light switch right by my front door and, in my dark little entryway, it's the usually the last thing I touch before I leave the apartment. I imagine that hanging my keys from this switch, as I recently saw on homedit, would mean I'd never walk out without my keys again.
Simply remove the switch plate and place a small neodymium magnet in the light switch. Replace the plate and voila it's magnetized! In the image above you can see that they placed the magnet inside the switch but you could also tape the magnet to the back of the switch plate.
