I'm glad you realized that was a scratch n' sniff Brew! We don't normally do Holiday Cards, mostly because it lands smack dab in the middle of exam season for my wife, who has much nicer handwriting than I do. So, that pretty much decides it though. I was going to send one to everyone I had an address for, but there were only 4 left on her site!
We get a lot of holiday cards and I'm always excited to see ones that are unique. There's another site out there, I think it's called
Pixelgirl Presents, that used to have a lot of custom cards too. I buy my wife stuff from there all the time (scarves, hats, etc.) but this year they didn't have any game related cards.
