1) Base your color theme & decorations on the birthday boys favorite team. If he doesn't have a favorite team then use your favorite team or decorate in a general football theme. Purchase football themed party supplies such as plates, cups, napkins and invitations in either your team logo or general football decorations.
2) For a unique tablecloth use green heavy paper and mark it up with yard lines to look like a football field.
3) Serve snacks (chips, pretzels, candy) in a football helmet.
4) Decorate with football posters of your child's favorite player (if he has one, if not then yours). If you have football jerseys hang them on the wall as well.
5) Balloons and streamers always add an inexpensive, but huge element. Use colors that match your team or the decorations you purchased. And of course, purchase a few football shaped balloons for a special touch.
6) Have all the guests sign a message on a football as a keepsake for the birthday boy.
7) Have your guests come dressed in their favorite team jerseys for fun.
8) Create signs such as "your child’s name for Game MVP" and hang them on your front door, garage door or in your house.
9) Decorate with helmets, football pads and footballs around the party area.
10) More football party ideas - Create pennants of your child's favorite team and hang on the back of chairs, have you and your child wear his favorite team jersey, dress stuffed animals in your football jersey's (baby size) and use as centerpieces.
Goody Bag Ideas: Use water bottles as the favor bag and fill them with candy and small toys such as football whistles.
