I make postcards. It's quick, easy, and I do NOT distress the edges. I learned that doesn't work well with the postal system machines.
Here I took a piece of cardboard, stamped it (Hampton Art Stamp) used Stickles, colored in some areas with my markers, sprayed heavily with Glimmer Mist and turned the heat gun on, to dry it out. And voila, I have a postcard, ready to send out today. I even have three stamps left from the holiday mail outs.
