The Tree is Up - which is utterly un-German and a new custom in our house. Since 2005, we put up our tree on the second weekend of Advent:
It's fairly traditionally decorated in red and gold, with limited edition porcellain bells that my best friend gives me one per year as well as a few very select wooden ornaments from my childhood. We don't use candles because I'm dead-scared of torching my house. Instead we have fairy lights plugged into a switchable socket, so that I can switch the tree on and off. Very German in its practicability.
(In case you're wondering now ... the garland from Day 2 is on a timer. Very electricity efficient ... and I can override it with a switch too!)
And then there was baking, lots of baking. I even participated in a Cookie Swap. The evening was fun but I won't do it again because I liked my wares best ;-)
