Over the years at West/Intrado/Notified, I have really enjoyed creating booths for national conferences. Typically, it is far more involved than just making a booth. There is usually signage (banners, widow clings, floor/stair/elevator stickers, etc.) around the event center to design as well as collateral and giveaways. This requires working with our in-house event planner, upper management for approvals, the event organizer, and multiple printing companies.
It's really great when everything comes together perfectly and our colleagues have rave reviews. Below, are mockups of several booths I have designed that were used. I have always asked for pictures to be taken of them (preferably without anyone in frame), but it rarely happened. I can share what I have upon request.
