Recently, I was invited to a steampunk wedding, and I really wanted to create a card to fit in with the day's theme. Prior to this, I had very little knowledge of anything to do with steampunk, so I did some research, and hopefully the resulting card didn't look too out of place!
I printed the two keys on the front, cut them out and covered them with a thin layer of 3D Clear Gloss Finish.
I added another key to the inside, and raised the steampunk tag slightly (on two strips of thin card) so that a gift card could be slipped underneath.
Note to self: Do more research involving Nathan Fillion as Castle!
