My sister has a beautiful way of creating floral holiday tabletop decorations that are low on expense and high on impact. Just take the cranberries you purchased over Thanksgiving that you either forgot to cook or meant to use as decoration but never quite got around to it. Yeah, those cranberries. Add them to some small vases, add water and then place some white mums. They last a long time, just refresh water as needed.
Mums the bloom for a white Christmas

Perfect!
