Yes, we went the cheap-o route with the 4X 6 postcard. Did you know that you can mail a 4 X 6 print?
I did add a piece of card stock to the back to make it a little sturdier. And, of course, I just had to stamp it? (I just couldn't send it out all white and plain.) As you can see we spent one Sunday evening recently signing our names. It is a tradition I enjoy. I am not sure why--the boys complain and see how quickly they can finish. It takes Lyndsi and Lexi a little longer--but they get the job done.
So Merry Christmas from our home to yours.
