Football Purse

This tailgating craft combines style with practicality. A football is the perfect size of purse to fit into the tight quarters of a stadium, and it couldn't be more festive. Use a team-branded football to proudly display your team and maybe add some bling to make it yours.

Team Flag

There's not really a more obvious way to show your team spirit than to hoist up a flag for all to see, so this tailgating craft is fairly obvious, easily customizable and especially reusable. It is also a fairly simple project that takes inside an hour to complete, not including the time it takes for the paint to dry.

No-Sew Fleece Blanket

JoAnn Fabrics has fabric for most NFL teams and many of the larger college teams as well, so this tailgating craft is a very practical and spirited project to keep all your favorite fans warm during the frigid late-season games. It's a straightforward project that requires fleece and scissors and many knots.

Homemade Pom-Pom

Celebrate first downs, field goals and touchdowns with a special homemade flair using this DIY pom-pom tailgating craft. With the extra effort and tender loving care, I'm sure homemade pom-poms lend extra energy to their team! And it's easier than one might think.

DIY Koozies

Beverages that are the wrong temperature are really a killjoy while tailgating: warm soda or beer when you just want a refreshing drink and cold hot chocolate or coffee when you're trying to stay warm are all preventable if you just use these homemade koozies.

Utensil Holders

This tailgating craft is a quick and easy project that really adds a playful touch to the spread at the food table. The utensil holders also serve as a sensible way to distribute the utensils, napkins and straws. Depending on the food served, a moist toilette and mints might also be logical additions to these perfect little pockets.

Team-Centric Drinks

I started following Snappy Gourmet because of this drink, despite the fact that I don't drink alcohol — the presentation is just so perfect, and if you haven't realized it yet, the Michigan Wolverines are my team. Anyway, what a fun and easy way to incorporate the team spirit theme into a party: use a fruity garnish in drinks to make a team-spirited statement.

Football Goal Posts

Goal posts on the food table really make a statement: they really let everyone know what sport the party is celebrating. This tailgating craft is a project that should make appearances at every football gathering you host. The posts take up very little real estate on the table for how visually striking they are.

Food Flags

The whole point of tailgating is the food, in my opinion. So highlight the main event with flags and fanfare, and a marching band if you have one. These adorable pennant flags are easier to assemble than a marching band, and they take up much less space.
