Outside, my only decoration is a wreath on the door. I used to do bows on my pathway lanterns, but they always looked bedraggled from the weather, so I stopped. I'll bet you are saving up tons of ideas for next year.
We hang wreaths with just a plaid bow from every light on the front of the house, & on the front of each window. (We use fishing line from the top of the window so the wreath hangs in the middle.) We don't do lights outside-just on the tree in the front window.
