Another way to easily change the look of your blog for the holidays is just to change the entire theme.  This can be a lot of work, but it saves you time messing around with graphics.  Here are some wordpress holiday themes I found.  Some will work even longer than the holidays.  If anyone knows of any places to get holiday blogger templates please leave a comment.
