The 1st thing that came to mind when trying to describe our lights is "Old Fashioned" because we have been using these same old lights for nearly 15 years. Many of them were passed down from family.
Our house really has no theme, just everything our family feels this time of year. We have several trees with 2 that come close to 10' tall, Santa on his train, 2 Penguins on Ice, Snowmen on Ice, a few Bears including Winnie, Candy Canes , several Wreaths, Snowflakes and much more. My 2 girls and I are adding lights daily, so it will just get better and better.
