The papers I used were already in my paper stash, so it was simply a matter of selecting colors and patterns that looked good together and using the punch on them. The 140# watercolor paper the 1x1 inch squares are adhered to had been cut for another project but never used. So without the need to do anything beyond creating 24 squares, the postcard went together lightning fast. I used my trusty matte medium to glue them down, then applied it over the surface of the card to seal it.
If you don't have any hand painted papers, you can use images from old magazines, calendar illustrations and any number of other "found" papers. Packaging materials often have very bold graphics and interesting typography that work well also. This postcard was one I made using black and white typography taken from magazine ads:
I didn't use a punch because at the time I didn't have one. I simply used a craft knife to cut the paper pieces into rectangular shapes. Then I arranged them on a piece of watercolor paper and glued them into place.
And here's a third postcard with a playful look. To make it, I punched out one inch squares from a magazine ad featuring bright colors and simple designs:
It may not be "high art," but making your own postcards is a whole lot of fun. You'll have the satisfaction of knowing the correspondence you're sending is one of a kind, and as such, it's sure to delight the recipient. And if you use materials that were destined to be discarded, you can pat yourself on the back for re-purposing them into mail art that's attractive and useful!
