We haven't had a real tree since I was almost one and found out I am allergic to Pine trees. Since then, we've also found out, that I am allergic to most coniferous trees...
We have a 7.5 fake srpuce. (Think tall and narrow tree.) I love it. We use regular size matte finished burgandy, green, and gold balls with smaller shiny and matte mixed pearl, gold, and burgandy little balls with little clear lights.
I keep things as simple as possible.
Other than that, we have stockings, a wreath, and a Christmas snow globe collection, thanks to the dear M-I-L.
