Here is a look at my Studio Setup. My modeling area is on the opposite side of the room. So when I need to paint from life, I just turn my easel around. Its on wheels so it moves easily. Sometimes, I setup a small pochade box so that I don't have to move my large easel. My large easel is on the west wall, and my modeling area is on the east wall. The windows are on the North wall. The South wall is for art supply storage and art books.
My Art table is on wheels, so its always in a different spot.
