We live in a townhouse. The grounds of our townhouse association are very beautiful and very well-maintained. When the weather is nice, there is a lot of traffic outside: people walking by, with dogs, with kids... to the shopping mall, from the shopping mall... employees from nearby business offices on lunch break... Right next to our patio and the room that I use as my office.
I did not want to use blinds or curtains on the patio door (I do not like either). Instead, I bought a a piece of wall décor, a large carved wood panel, at TJ Maxx. It had a small scratch and was on sale for $50.
