A live wedding painter to capture your ceremony/reception space and your guests

A wedding wheel with fun “prizes” for your guests to spin

Arrange ceremony seats in a circular pattern around the couple so that everyone can see.

Provide coasters that help people keep their drinks while dancing.

Give guests to-go boxes so that they can take cake home.

Create cool door tags for guests who are traveling and stay overnight.

Have a creative Mad-Lib RSVP card

Put photos of yourselves at different ages corresponding to table numbers for your guests to enjoy.
Make your ring bearer a ring security guard.
Make/buy an inscribed handkerchief for your flower girl that she can save for when she gets married.
Add a pop of color on the tulle under your dress.
Instead of throwing rice….
Compile addresses of all of the guests at your wedding.
Leave fun facts about yourselves on the tables.
Pin something sentimental on your bouquet.
Make your own Instagram hashtag that your guests can use. Not only is it fun for them, but it also allows you to see all of the pictures your guests uploaded to Instagram in one search. We love when couples get our tv packages because we get to play their photo montages, their live Instagram feed and anything else they choose to show. 
A “Please Call Anyone But the Bride” list of phone numbers for your wedding party to keep stressful, last-minute problems away from the bride on her wedding day.
Include a space on the RSVP where guests can request songs to play at the reception.

Play The Shoe Game at your reception. The bride and the groom are seated back to back and each hold one of their partners’ shoes and one of their own. Then, the maid-of-honor, best man, and other guests read a list of “who” questions about the relationship (“Who does most of the cooking?”, “Who made the first move?”, etc.)  to which the bride and groom hold up the shoe of the person who best fits the answer.

Have the groom write a message to the bride on the bottom of her shoe the morning of the wedding.
 ….or have bridesmaids do the same thing. It’s said that whoever’s name does not wear off by the end of the night is the next to get married!
Give each table a song name or lyric. When their song plays, the whole table has to get up and dance. If you are doing a buffet dinner, the song could also be the table’s cue to get food.
Create a piñata for you to break open on your first anniversary filled with notes from your wedding guests.
Have guests sign a calendar with their birthdays, anniversaries, etc.
Guests throw darts at balloons filled with paint attached to a canvas. You keep the art.
Leave advice/prediction cards about your future together for guests to fill out.
Number your RSVPs with a black light or regular pen so that you know which guests responded or to help read illegible handwriting.
Take a picture of the rings with a newspaper from the day of your wedding.
Throw heart-shaped confetti made of pages from your favorite book.
Instead of asking for registry items, let guests donate to your honeymoon fund (also known as a nice way to ask for money as a gift).
