Think of your wedding as one big party. After all that's what is is. A commitment between you and your partner celebrated with those you love. Just like those intimate dinner parties or elaborate Halloween extravaganzas you are used to throwing, your wedding needs a theme.
No, I'm not talking about everyone showing up wearing a big bra and Dolly Parton wig. (Unless your theme happens to be "The Best Little Whorehouse in Texas"). Choose a theme that means something to you both. Perhaps your favorite sport or activity. maybe you want to choose a color theme. But whatever you do PLEASE be creative.
Be different. Use a barn and make it a square dance. Maybe you are a great bowler, use a bowling alley. Something that celebrates what you like and who you guys are. What ever you do, make it a unique and memorable experience for you and everyone you love!
