I picked most of my fifteen holiday mugs up at garage sales. One of them, I'm not sure which any more, was a Christmas gift from the oldest grandson when he was just a little guy. I used to hate my two California Raisins cups (they aren't that pretty), but now I like the fact that they're dated on the bottom (1988) and they bring back memories of some old commercials that were popular when my children were teens. There must have been a lot of those made, because they don't bring much on Ebay.
I intend to get into the spirit of this Christmas season by hook or by crook!
While I'm on the subject of mugs, look what Lois-on-the-web found? A mug-warmer that works off a USB port!
