Oh, and the windows are decorated for Easter too!
You are so good about that! I decorate a little bit for Christmas, of course, mainly in the form of a tree but with a few other little things.
On Halloween, I generally drag out the box of stuff at about 5 p.m., put up a few things in the front windows and on the door and that's about it. When my kids were little, we went much further -- I had them draw faces on ghosts made of Styrofoam balls covered with white cotton and hung them in a tree. I had them stuff clothes to make scarecrows wearing Halloween masks. I wove that spiderweb stuff on the porch rails. And of course we carved jack-o-lanterns.
On Mardi Gras, I dragged out the purple green and gold Mardi Gras lights, wrapped them around my dog and took a picture, then hung them in the front window.
