Cheap wine glass + tea light candle + paper cup with bottom cut out. great idea for center piece ideas. can even take a clear cup with bottom cut out and cover in craft paper. I like it without the shade.
Upside down balloons with no helium needed.Slide a marble into the balloon before blowing it up, then suspend from ceiling with scotch tape, maybe poster tack - play dough stuff. It is a great idea for a party!
