Mine is set in a U shape too, I bought 3 computer tables that were on clearance, set them in the U shape, and have 3 machines set up. My embroidery, my "Beast", (a Janome 1600P, it only does straight stiching), and my serger. It's so easy to use them this way. I have a sewing chair with wheels so I can just turn from one to the other. It's nice to have my embroidery machine running while I am sewing on the beast at the same time!
