Natural turf is another easily accessible accessory. Go outside and dig up some grass to decorate your Super Bowl tabletop, Trigg recommends.

The food, too, can be great décor. Trigg offers guests guacamole served in avocado halves, reminiscent of the shape of a football.

Lee said she takes at least two weeks to plan casual gatherings in order to give herself enough time to shop for the best decorations and centerpieces.

Her party supplies for a Super Bowl shindig might include team color tablecloths, pom-poms, cheer sticks, craft paper and Astro Turf, she wrote in an email.

Trigg and Lee agree that, aside from great decorations, hosts should consider who's coming to the party and how they might commune. Lee calls this the "energy of the room."

To keep the party exciting, Trigg plans games for kids (such as a best team cheer contest) and competitive BBQ throwdowns for the adults.

Pino suggests turning the big game into a party game. Provide guests with penalty flags to throw during the famously high-concept commercials. "Bad commercial! Bad commercial!" he shouted with glee.

Not everyone will be glued to the tube or the grill the entire time, Trigg said. She makes sure to provide multiple areas for guests to mingle.

"The Super Bowl is more than just football," Lee wrote. "It's a fun celebration, and everyone can appreciate that."

"At the end of the day, it might not be your favorite team in that last final game, but it's more about bringing your friends and family together, honoring that tradition," said Trigg, whose Atlanta Falcons just missed out on a trip to the big game New Orleans this year.
