I will start on Friday, this is my favorite holiday and I go all out! It takes me at least 3 full days to decorate the inside of the house. Dh takes care of the lights/decor outside.
I have a total of 9 Christmas themed trees to set up throughout the house. A Christmas village on the credenza. Lots of quilts and cross-stitch pieces to hang or drap around. I wrap the staircase with lighted garland. Oh, man...there's so much to do. And my little ones can only do so much (don't want them to break anything).
