Article: Postcards usually have dedicated spaces for the message as well as the sender's and receiver's address. If it is a homemade or non-standard postcard with no dedicated spaces: draw a vertical line down the middle of the card while it is in a horizontal position, then draw a horizontal line splitting the right half in two. Use the left hand side for the message, the upper-right for your own address, and the bottom-right for receiver's address. It is not essential that you include your own address. As long as you write the receiver's address, they will receive your card. If you're traveling, you may not expect a reply – or you can give your correspondent the address of the next place you'll be staying. See How to Write a Postcard. If you're mailing it to yourself, write a memory on the back of the card; if you're mailing it to a friend, add a short message to let them know how you're doing. Try to give the recipient a brief snapshot of your experience. You don't need to write a novel – the very act of sending a postcard, however short, is usually enough to show a person that you're thinking of them.  Again, make sure to put the stamp on first. This way, you won't end up writing where the stamp covers. It's important not to write too low on the postcard. Most of the time, the post office will print a barcode or attach a sticker across the bottom of the card in order to send it where it needs to go. Try to keep at least a finger's width between the edge of the postcard and the bottom of your message. Find a post office or a public mail drop box in your area. Make sure that you've added the correct amount of stamps and properly addressed the card. Once you're certain, mail the postcard as you would a normal letter. If you're abroad, allow at least a week or two for the letter to reach its destination. Some office buildings, government offices, or community centers may have a mailbox. If you are at a hotel, the front desk will often mail your postcard with its outgoing mail. If you can't find a place to mail your postcard, ask the locals and other travelers.
