12 heavyweight 4”x6” matte finish postcards from my 100 Day Project #100daysofbluepen. Each set contains twelve different pattern designs from the series – 6 that are blue & white, and 6 that feature splashes of color. These lux postcards make a great gift to share with friends, drop someone a note, or frame! Can be mailed as postcards, or add a set of 12 self-sealing kraft envelopes to keep your messages under wraps.
