I REALLY want the theme for DS' party to be dirt. Not construction necessarily and not dirt bikes...just dirt fun. I want to be able to do different things with dirt without being tied down to just dump trucks, just bugs, just dinosaurs....etc.

The problem is that the only invitations that I can find are less general than that. Can anyone help me find an invitation for a dirt party? Or give me any suggestions on how to customize one? Thanks!
