Well Hello Amy I just recieved your message regarding those columns. The panels hanging from the walls are called Shoji screens wich is japanese room dividers and window treatments. I got into those about 8 years ago and realy enjoy making them. Normally rice paper gets put in the panels wich is a really cool way to filter light. That particular customer loves those and paints water colors on the rice paper panels wich she changes every couple of years. Those panels on that job cover a 13' window so its a long track made for sliding pocket doors. The track cost me aboout 50$ at the time. Be Well William
