I'm not one of these people who decorates much for Christmas in advance of the fact - our tree goes up a max of 2 weeks before (this year, it's going to be the 14th) but of course, there are some things which come out beforehand... the advent calendar of course, and just a few other things, like replacing a few of the pictures on the wall with some seasonal cross-stitches (some simply wintery, some more Christmassy)
(this one was a gift; the others are all ones I've stitched myself)
And there are a few other things - this Christmas cushion, from a secret santa exchange some years ago, for instance...
and the Christmas quilt, which I want to use for longer than just a few weeks, but not for the whole year. There is also a set of lovely, appliqued Christmas placemats which I love, but which are too nice to use... Maybe a photo of them later in the month!
