For my second card, I debossed the same cover plate I used for my first project, and then stamped my random star pattern (again using a template cut from a plain piece of paper). Even with a template, I can't line things up very well- Ha!
Aywho, there doesn't seem to be any difference, so perhaps you'll find it easier to deboss your desired images before you stamp.
Here is my second card:
