C.,
If your team has the smaller hand held megaphones, place them down the center of the table, put the handles of the pom poms in the hole in the top of the megaphone, use the cheerleaders skirts under the megaphones like a placemat or table runner. Ask the team and the cheerleaders if you can borrow their jerseys or tops. Slide each one over the top of each chair back. Simple décor, you haven't spent a dime.
If you don't have small megaphones and small pom poms, you can buy them at Party City. Hopefully you can use the teams stuff, you won't be stuck with these items afterwards.
If you do have to buy them, write their names on them and give them away. :)
Also if you have a chandelier if it is the right shape you could tuck pom poms up on it. The streamers
can hang down.( I hope this makes sense?) It will look pretty with the light filtering down.
Anyway, I hope it all makes sense. I have lots of ideas, please feel free to contact me anytime, I would love to share more. :)
God bless, and have fun

You can hang whistles, just tie them so they hang down from the pom pom some.
