Themes: Of course this seems like a no brainer: red, white and blue. While that’s true, there is no reason you can’t combine two themes. For example, if you are near a body of water, pools included, you can have a beach-theme patriotic party. Decide if you’re going to stick with a traditional red, white and blue party or add a second theme. Then, base your decorations, food and activities off of your decision.
