Postcards can be any size and can be mailed Naked, written on and stamped, or in a clear sleeve or envelope. Anything mailed in an envelope should be mailed in a decorated envelope of some kind. If mailing a shaped postcard or envelope, you will need to include extra postage to cover the non-machinable fee. Please include your user name and swap name so that you may be rated.

Have fun.
