Here's an idea... save time by just putting out decorations for all the holidays at once!
These homeowners have it covered with a Santa "Welcome" sign, a patriotic wall hanging by the door, two pumpkins hanging from their porch just waiting to be baked into a Thanksgiving pumpkin pie, and a Halloween ghost crouched by the steps. When they answer the door, perhaps paper Valentine's hearts fall on your head while you're presented with a birthday cupcake and a candle to blow out!
(Make a wish!)
What's your favorite holiday?
