Give pretty spice or candy containers a new life in seconds by turning them into refrigerator magnets. Place a small, powerful magnet inside the back of an empty tin, which makes the tin itself magnetic. (Nonmetallic containers will work if you stick an adhesive magnet on the outside.)
Lastly, teach your kids to organize! A simple magnet board (this one is just a painted cookie sheet) of chores to-do will help them learn responsibility for their things so you’ll worry less about their rooms being ready for a home tour.
