1. Use the palette light and limited; go for a contrasting color as an accent in order to bring specific elements in focus.
2. Keep the window decoration simple.
3. Use a modest chandelier; it will make the table seem larger.
4. Consider opening up the ceiling; a tray or vaulted ceiling will make the area seem more spacious and adds the surprise of unexpected proportions.
5. Mirrors increase the perception of space; use them on at least on two walls.
6. Choose a round table. The size of the room will seem larger. Plus, you can always squeeze in an extra place setting, especially if the table has a pedestal base.
7. Choose chairs with clear lines. Consider sheer slipcovers. Chairs without arms require less space to maneuver in and out of.
