Illuminated pumpkin topiaries are a gorgeous way to decorate your front doorway or fireplace for Thanksgiving. On the “Harvest Party” episode of my TV show “Weekend Entertaining” on the DIY Network, I put together a stunning 3-tier pumpkin topiary with a cut-out design and lit it up with holiday lights inside. Best of all, these pumpkin are fake so you could use this display year after year.
