Services like Instaprint are popping up at many affairs, proving popular with guests as a tangible record of their active social media use. At a fashion show held by USA Network in New York, even the wall the machines were mounted on sported the hashtag, motivating curious attendees to snap a photo and post it via Instagram.

Staffers are a common sight at events, and some event producers have put hashtags on the outfits worn by greeters, caterwaiters, or even hosts. In February, the South Beach Wine & Food Festival advertised its official Twitter phrase on the T-shirts worn by participating chefs like Rocco DiSpirito.

Just as common as a red carpet are the rope-and-stanchion barricades that denote an entrance or V.I.P. area. Among the ways the Art Gallery of Ontario displayed the hashtag for its annual Massive Party fund-raiser on April 19, was the use of small signs placed atop stanchions.

The colorful plastic and paper wristbands used at concerts, festivals, and other big events can be customized to show a designated hashtag. To encourage guests at its Party in the Garden fund-raiser to upload photos via Instagram, the Museum of Modern Art in New York handed out entry bracelets printed with the hashtag #PitG2012.

Invitations and programs serve as physical reminders of an event's basic info—the date, time, location, and even dress code. An additional step would be to add the hashtag to such materials, which is what the Shorty Awards did in New York on March 26.

Bars are almost always the most crowded areas of an event, and in addition to displaying the affair's signature cocktails, drink menus can be marked with a hashtag.

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.

When events offer beauty and grooming treatments, guests are likely to feel compelled to share their post-experience transformation, whether it's a new hair look or a fresh manicure. At HBO's Luxury Lounge during the Emmys in Los Angeles, mats under mani stations encouraged social snaps for guests receiving Marc Jacobs Beauty manicures. And at Herbal Essences lounge at BMF's Hard Rock Hotel party during Lollapalooza in Chicago, hashtags on nearby signage encouraged guests to post beauty shots.

Hashtags that encourage interaction on site through gamification or another kind of activity are sure to facilitate broad interaction online as well. At Target's Feed U.S.A. event, menus encouraged guests to interact and mingle with tablemates through social media prompts on menus.

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.

Every guest is likely carrying a smartphone in his or her pocket. But making social sharing as easy for guests as possible can only further encourage the behavior—so try printing hashtags right alongside displays of smartphones or other devices. At Samsung's tent at the Life Is Beautiful festival in Las Vegas, attendees ordered free frozen yogurt and designed T-shirts from devices at stations emblazoned with the activation's hashtag.

Sure, promoting hashtags within the boundaries of an event can get guests interacting. But put them outside the event's official walls and you're more likely to capture a bigger crowd. At the Cannes Lions International Festival of Creativity, a 3-D projection of tweets using the official event hashtag appeared on a 35- by 65-foot billboard. The digital activation, created by Incredible Machines, ran at night, while during the day the billboard showed a static image of the hashtag printed on canvas. Similarly, AOL placed its hashtag on a giant billboard outside the venue of its upfront event during Advertising Week in New York.

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.
