Activity for Stephanie

I am designing my RSVP cards and I am doing them as postcards. But I kinda think they look to plain. Is it just me? this is the front and the back

These aren't completely done. I have to get names of his grandparents, but for the most part they are. What do you guys think? I just added the second one to see your thoughts on that.
