What about a round postcard? I created a round postcard in a mailable size (4 1/4"). The front of the postcard is decorated with circles. I used cardboard, patterned card stock, plain card stock and wallpaper. To cut the circles I used my Cricut Expression for the postcard. tor the smaller circles I used my Coluzzle and paper punches. I finished the card with writing hello and hi and the smallest circles. At last I added dots and stripes on and around the circles as a finishing touch. I hope you like this postcard ... I love it!
