Our main level is "L" shaped, kitchen at one end, living room at the other with the dining room connecting them.
For years now, the living room has been my sewing area,though we use it for an extra eating area when we have company.
My husband build shelves on the wall for my stuff and we bought an antique oak table for me to work on. Just recently, we swapped out the tables, so the oak one is in the dining room and I have the former dining room table, also oak, but with a formica top. It has two leaves that I can add when I need more space.
When I need a LOT of space, I clear off both tables and use them both!
