Postcard Designs
If you’d like to send a postcard to the White House or to a legislator, here are some printable designs. Just print on regular paper and cut into quarters. Flip each card over, draw a line down the center and voilà: instant postcard. Postcard stamps are currently 34¢, so you get a lot of bang for your buck.
