Just posted some of our outdoor lighting over at my Kitchen Table blog, so now I'm adding just a bit more. We didn't have a lot, but more than usual. The trees that I posted about on my other blog are new this year, so you may wish to go over and read more about them, where they are located and how we chose to decorate them.
The flag at the top of this post is one we have on a flagpole mounted on a tree out by the end of our driveway. We have it illuminated with a small solar light all year round, but Mr. T hadn't thought to get a nighttime photo of it until he was outside snapping photos of our other lights. It looks a bit Christmasy since it's on an evergreen tree.
Now the lights below are some that we light up every year. These are the strings of colored lights with the large bulbs. We've had them up there for years, tucked just inside the roof line of our garage. We just have to replace a bulb or two from time to time. Sometimes we place a lighted star (white lights) centered just below these.
The photo below pictures neither lights nor decorations, but our stacks of cookie tins that are keeping frozen on the front porch. They are a little bit decorative, I guess -- and people do light up when they see a plate full of Christmas cookies!
