I just made my first postcard! I made it for a swap. I really like how it turned out!
I used some poster board, cut to 6 x 4.25 inches. I made the graphic for the back of the postcard in PSP.
Permanent Glue Stick to adhere the graphics to each side of the poster board. Then I covered the front and edges with one thin coat of Plaid Royal Coat Découpage Finish.
I like how it turned out! I will be making more of these in the future. They are just a larger version of an ATC (Artist Trading Card)!
