This idea can be used for many celebrations! I found this photo in a book called Celebrating Home and my immediate thought was of course 4th of July!!
but after looking more at the photo and seeing the cute tricycle I thought of a baby shower for a little boy! How cute would this be for the All-American baby boy. Everything in red, white and blue, the tricycle, flags, etc.. Did you notice that there in the clear vase is old poker chips in red white and blue. It just adds to the table. You could have red, white and blue refreshments and of course watermelon. Your invites could also take on the theme. 
Or ....how about for a birthday party for your dad or grandfather especially if they happend to serve our country in any way, Memorial day celebration, Flag day, Labor Day, Celebration for the return of any service people, how about an anniversary party for the all-american couple, or throw a party just because you love our country and red white and blue!
Notice how they used dish towels for placemats, non matching blue glasses, white plates, mismatched old chairs and hanging in the windows are star cut-outs attached to red and blue ribbons. Cheap and yet it all comes together and looks fab! Share other celebrations that might work for this theme.
