I usually do the main tree in blue and green to match the colors in my home. There are touches of white and silver too.
I hunt out all different kinds of blue and green ornaments and add a few each year.
Look at Bentley being a good boy!
You can see that the top and the bottom of the tree aren't finished yet...I have to get the ladder for those top branches. I still have more ornaments, the tinsel and the angel...which is always put on last.
