Mike, thank for the comments on my card, glad you like it. As far as the borders there is a method to by madness. Half inch borders on 5x7 paper gives an image area of 4x6 which matchs the aspect ratio of a 35mm negative. I did end up with a slight crop to eliminate the edge of a window that didn't show up in my view finder.
I also wanted to thank Laurent and Fotogys for their comment as well.
