How to create a half or partial wall?

[Tammster]

Thanks so much! I used both of your ideas & they both worked perfectly!

The granite bar above the counter looks perfect now. I made the flat bar top about 8 inches above the counter & then made a 1 1/2 inch thick/8 inch high connector.

I never thought of a solid rail, changed to a regular white wall. That was great.

My remaining problem (at this point) is I have an outdoor "atrium" off of the master bath. Basically, it is three concrete walls that are only 6 feet high. No mater how I change the room or roof, the walls stay high.
