Make It Snow At Your House
Many people associate the end-of-the-year holidays with colder temps, and most post cards that you can buy about Christmas and New Year's include some reference to snow; whether it be a snow man, snow balls, a snow-covered village, or CJ making yellow snow - most of them contain some reference to snow.
(For those with "Clickaphobia", it's just a link that will take you to a website that works with a Google Map App that puts the photograph linked to the address that you enter into a snow globe. Don't worry, there's no picture of CJ making yellow snow!)
Put in your address, take a screen cap of your house in a snow globe, print it and use it as the image for your Christmas cards!! (You can thank me with pumpkin pies, if you'd like!)
