Simple centrepiece ideas - If you can make Jell-O, you can handle creating this centerpiece. Just combine six boxes of Jell-O (the color of your choice) with half the amount of water required. Put the mix in a glass vase and leave it in the fridge for half an hour. Then push flowers into the semi-firm Jell-O.
