I don't know about you but I do some of my best thinking under the blow dryer in the morning. As a result, there is always something I want to write down but I don't have any paper nearby. What I do have is 3 giant mirrors and a dry erase marker. Put them together and you have a wonderful place to write reminders, Scripture, love notes, phone messages, your to-do list or the next day's events. I even have a list of items on the mirror that were donated when I cleaned the closet because I didn't have any paper. That is one list I haven't lost yet!
It is difficult to miss a note when it is blocking your view as you put on makeup or brush your hair. It is even more difficult to lose the mirror and wonder where you put it. : )
I write notes on the kid's mirror as well, and they draw pictures. My sister Auntiebug uses the mirror backsplash in the kitchen to write last doses of medications or reminders. It also works on windows, glass shower doors, and possibly white appliances. It wipes off with a tissue and any residue left comes off with window cleaner- no big deal.
