Stockings and candles are great on the stairway (as long as you don't have small children or a dog).
Or what about adding some greenery to a window or bench?
This is one of my favorites. Take a cloche and add some sparkly starfish or pinecones and a bow.
Wrap some greens around something already up on your wall.
I even got creative with some burlap and made a runner. Burlap is very inexpensive (although be forewarned that it smells and sheds!) I even added a monogram below.
So keep it simple and beautiful. I'm off to find some greenery and who knows what else!
Have a great day.
