If you are planning on mailing cards to loved ones for Christmas, don't forget to stamp them and to write the FULL address of the card's recipient. You need to write at least your mailing address in the upper left hand corner of the envelope just in case your card cannot be delivered.
It is vital that all address information is included on the front of your Christmas cards such as this:
703 N. Second Street
It is also helpful if you seperate all of your envelopes into a pile for local card recipients and another pile for those people who do not live in the same county in which you life. Place a rubber band around each pile of cards before you mail them. That will help the postal employees to gather and deliver the mail quicker.
