Maybe what your thinking of is the "Picture Package" feature now available in 7. This lets you create various layouts like (2) 5x7. If your postcard is not larger than that, i'd create one for the front and then stwitch layers around and create one for the back. Print out the "Front" (let them dry) flip em', and print the back. This will let you get "two up" on a page so you don't waste paper. again this is JUST ONE WAY to do it. as with anything, there are differents ways to do anything!!! :)
