I have done several postcards this year, given as birthday cards through the mail.  The one below used a fabric and paper background with decorative stitching and a piece of metallic mesh.
This one is one I would like to expand into a larger piece.  Often I do postcards to play with an idea, and then I can enlarge the design and work in a larger format. 
This postcard below is made using my felting machine.  I love doing felted postcards because they work up so quickly!  I used several different yarns, some cheesecloth, fabric and mohair to make the body of the piece.  I then embellished with beads.
I made this one a while back using sheers on top of a shiny white fabric.  I attached the jugs with Misty Fuse and stitched around the edges to hold them down.  
I also made this one a while ago.   It uses rusted fabric torn on a black background.  I then stitched in a square spiral and put some altered web ribbon on the front.  I painted gold Lumiere in some of the holes .  I try lots of different things on postcards; they are just too much fun!
