For NYE I punched lots of cans and put in tea lights for some ambience around the garden. But now that we are a week or three into the new year, they're still there, just because I like the look of them from the kitchen window. When it's not raining and the wind isn't blowing, I light the candles in the cans when it's dark. Only thing that would made it look even more beautiful, is some snow. I hate snow, actually, but for half a day, so I can make nice pictures, I can handle it.
Very simple, but I love the result!
The snow stars on the windows I drew with a chalk pencil (bought at a stationar's shop).
