In the process of a living room remodel I have removed a load bearing wall to open up between dining room and living room. I have it supported with temporary braces for the time being, and eventually plan on installing a knee wall with columns from the top of the wall to the ceiling. These will need to be approximately 3 feet, and will most likely be painted white.
I have had no luck with finding columns of different lengths. All I find at the borgs is floor to ceiling columns.
If I had a lathe I would plan on turning some, but I don't, and can't buy one.
