Here's what the tables looked like
Not made by me, but this was handmade by a friend of my husband's to hold the cards
My completed guest book
And here's what we looked like. My hat is vintage and I found it at an antique store (earrings are, too, but you can't really see them in this picture). I made his boutonniere as well.
It was super fun and a lot of our guests followed the theme and dressed up in 50's looking outfits.
