Today’s printable is this free personalized postcard. The design is blue and black, with a pattern of pointed wavy lines in peaks and troughs. A small blank box sits in the center of the postcard, on top of this pattern. Inside of this box you can type whatever message you see fit (so long as it, um, fits). This personalized postcard is hence perfect for when you forget someone’s birthday and/or would like to simply wish them well.
