1. Put Them Where Guests Snap Pics
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.
