Go rummage through your Christmas decorations and take pictures of them in different settings. I take photos of old things if I am completely bored out of my mind. Actually I do this even when I am not bored. 🙂
I took an old ornament and set it in the grass and in the tree and it looked pretty cool.
One thing that makes shots like this work is the narrow depth of field. Shoot low ISO and low F-stop if you can. It will make the shot almost abstract.
