The first card is a gnome diorama from http://www.fredflare.com/. Kinda silly but also kinda expensive...
The next three are from rockscissorpaper and the last is by Frederick Beck. His designs are sold all over the web.
But if I have the energy, I may go in a completely different direction & take a photo. Not a traditional photo. My husband has sat on Santa's lap with me... we looked ridiculous, which I like. One year I sent a photo of us at a holiday party, and last year our cards were of a Shag print.
By the way, if you saw my earlier post - invitation obsession - I chose the last one from http://www.rockscissorpaper.com/. They were titled "Golden Globes." I wonder why I was drawn to those? :)
