Dear This Old House,

In 2006 we moved into a new home and all the walls are the same color. The living room area is open to the dining/kitchen area. All the corners in the open area are rounded. I am wondering if I wanted to painting the dining area wall a diffent color than say, the hallway, how do I stop one color and start the other on a curve?

Thanks for your help because I'm getting ready to tackle some paint.
