I have always loved nativity scenes.
This is a picture of my Mom's gorgeous set. The figures are around 8" tall.
She has it set up on her sideboard.
Woodward's downtown used to set up a glorious full size nativity and when they went bankrupt, The Bay used to put it in their window, but I haven't seen it this year.
I have our set up on the mantel, but it is very simple.
