It’s called “I’m running out of time and I need a centerpiece”… Take a clean glass cloche and fill it with some locally made glass ornaments then up turn a glass pie or cake plate onto the cloche, turn everything over, and make sure no wise ass lifts the cloche up. Takes less than 5 minutes to do.
Place a bowl filled with red and white peppermint candies nearby for more holiday feel. This is what you do when you’ve run out of time to do something more elaborate. :)
