I used Modern Postcard for laying out and printing announcements for my exhibition. I am so glad that I did. All I sent them was a photograph and the text. They did wonders with the layout. The colors of the photograph are perfect. The layout is neat and easy to read. When I hand people the announcement they are all very impressed. Modern Postcard, YOU ROCK.
