When I was a kid, it was probably this plastic Santa:
It had a hole in the back to insert a bulb to light it up. We usually had it unlit, but I liked it just the same. Was something classic and simple about it that appealed to me.
There was a Mrs. Santa, as well:
My brother and I had found her for sale at a local discount store - Kerr Mill, for those who are curious - and we planned to save our money to buy her. And then the store burned down, Mrs. Claus along with it. We never got her, and I am unsure whatever became of Santa.
And now, with kids of my own, we have so many decorations and memories attached to them, it is hard to choose!
I love the new framed Santa picture my wife got as a gift, almost identical to this one:
My nickname for my daughter is Snowflake,
so, each year I give her a different snowflake ornament:
And my youngest son got the Elf on a Shelf a couple of years ago,
and it is a fun decoration & activity:
So, yeah... I like Christmas decorations!
