I'm turning into your neighborhood Wally World

Christmas even before Halloween or Thanksgiving!
When do you usually aim to schedule sessions by if they want Christmas cards to send out to people? I'm thinking of October/November.
What props do you use? What backgrounds (colors, papers, scene backgrounds, outside pictures, christmas tree farms, fireplace)?
Do I need to build a faux fireplace or is that going too extreme?
I know the tri-fold cards have been a huge hit last year (maybe the previous year too). Are they still going to be?
