I hate abrupt changes, too. So I keep a little bit of each holiday up all year long. A Valentine here, an Easter bunny over there... Even if it's a nutcracker or a snowman in the heat of July and August, it makes me happy so to heck with everyone elses ideas of what is proper.
I have a sign just outside my front door that says it all. It has a trinket from every holiday; a bunny, a turkey, a shamrock, a pumpkin, and a Santa head all dangling from the sign. The sign reads; "Happy Everything" and that suits me well.
By the way Wash, I love your idea for a Christmas present to your mom. How perfect.
