Here's the way Christmas tree decorating works at our house; I decorate the big tree and the kids have small trees of their own that they decorate. That way my tree looks the way I want it to and my mom-guilt is assuaged because the kids still get to use their funky ornaments and decorate to their hearts content. One year Dagny re-decorated her tree every single day and Dane used his Star Wars figures as ornaments. That's something that I wouldn't let them do to my tree, so our tree decorating solution is a win for all involved.
Every few years I'll do something completely new with the tree. I went through a gold phase, then silver, one year I did everything in blue and silver. (Steve refers to that as our Chanukah Christmas) When the kids were younger I would match the decorations to their Christmas outfits. Yes, I'm that crazy.
