You may be surprised to learn that Taylor Rental sells merchandise as well as rents things. In our area, they probably carry the largest variety of football themed decorations. They have different types of centerpieces, including honeycomb and some with drooping or dangling pieces. They also have cutouts to decorate your walls or tabletop. Taylor carries one of the most unusual decorations I've seen in town. It is a large (probably 20" tall) blowup football. (It's like a beach ball but shaped like a football.) The nearest NFL team is the Tampa Bay Buccaneers, and Taylor sells plates, napkins and cups that are printed with a Buccaneers pattern. I also remember seeing some noisemakers that would fit right in with a football party.
I know they sell a few more things that would work with a football party, but I've forgotten what they are. While the prices are more expensive than Dollar Tree or Wal*mart, I thought they were still reasonable.
If you're having a big party and are looking for something fun, Taylor can rent you an old fashioned popcorn machine. You know, the kind that stand maybe 7' tall and have big back wheels.
Or, if you're serving hot foods in a buffet setting and want to keep the food hot, Taylor has several type of food warmers you can rent.
As you can see, Taylor can supply your party needs in many different ways.
