Social Media

If your event has an oversize prop, eye-catching decor piece, or some other feature guests are likely to want to photograph, that element is a smart place for a hashtag—and it's bound to make its way online throughout the night. For instance, a Los Angeles event for British Airways and Variety saw hashtags splashed in the front windshields of traditional British black cars. Similarly, Diesel printed the hashtag for its Reboot campaign last September on large-scale installations in New York's Union Square.

Sometimes, it's not the biggest message that makes an impact, but the subtle and cleverly rendered one that gets guests' attention. For a look that was well integrated with the venue's existing decor, Pandora launched a new jewelry collection in Los Angeles and emblazoned the Mondrian hotel's bold oversize planters with hashtags.

Turning tweeting into a competition drives major social media engagement—not to mention huge buzz at the event. During Mercedes-Benz Fashion Week Swim, prompts directed guests to use a tweet-operated Polaroid vending machine at the Ocean Drive Sun Covered Pool Party.

Putting hashtags on food isn't just a tasty idea—it's Instagram bait to boot. An event invitation to the Time Warner Cable Studios pop-up in New York before the Super Bowl came with a hashtag printed right on top of a cake.
