I used the Doug's Outer Space set from Lettering Delights. I thought it turned out great!
Here is a shot of the back. I used a variety of stamps and at this moment, I can't remember exactly what sets they were. I'm pretty sure they are all from Emma at My Creative Time though! Except for the To: and From:, those are from Joy's Life. If you haven't checked out Emma's stuff, go over and see it! She has great stamps and dies!
Thanks for stopping in!
