Normally we just do the tree, and a couple festive candle holders... oh and some xmas crafts from school.
This year, depends on the kitties. We put the tree up, with no decor on it just to see how it goes over.... If the kitties behave, we'll try some decorations on it.
If they don't behave, then the tree is going in the rec room where the kitties don't go unsupervised.
In the past I've typically decorated a LOT for Christmas. This year I dunno though. I've put the tree up, but not much else. (All of my Christmas things are in storage...so I just used what my mom had).
We mainly just do the tree. I do have a nice nativity set that I put up that I got for my birthday a couple years ago, but other than that not much.
We're also the scrooges on our street, the only house on our street that doesn't put lights outside. Our next door neighbor used to be the same, but this year she put lights on her bushes. Lol.
It varies. When we put a tree up, that's pretty well all the decorating we do, with the exception of a pretty bow here and there. The last couple of years, there's been enough chaos in the house and not enough energy to do much about it, that we've just draped a garland across the valance on the living room window. We did that when there were kittens in the house and found it attractive, so it's our fallback. I'd like to get back to doing a tree, but I have a hunch it's not going to be this year.
