Long before the arrival of the pilgrims, this country was populated by people who moved, and that spirit of mobility has not waned over the centuries. An average of 43 million people in the United States change residences each year. If you are among them, a simple card containing your new address and telephone number, sent to family and friends, saves much puzzlement and ensures that birthday greetings reach you on time.
What you send need not be fancy -- the post office even provides free postcards for this purpose -- but a new home is something to celebrate, and custom-made announcements are one way to do just that. Just be sure you can finish your project in time: The post office advises sending out change-of-address cards one month before you move.
When you've moved, everyone wants to know where you've gone. Show them with a map. This postcard depicts your new neighborhood; a punched hole marks your house.
