'Twas the night before Christmas
Gotham slept without fright.
No criminal lurked
Thanks to the Dark Knight.
If Afred Pennyworth decorates the Batcave for Christmas---let's admit that Bruce Wayne is not the sort to get into the Christmas mood--then he would surely put up a wreath like this one over the entrance. Kat and Cam of Our Nerd Home made this wreath using a foam core backing and Christmas garlands. You can find instructions on how to make your own here.
