Most of us use these two methods when we decorate, as it's not feasible to change everything at once, and if you're renting some things can't be changed at all. The combination works every time. If you have a home, you have walls, and whether they're high or low, they are a canvas to dress up any room.
Tall walls imbue a room with the airy, luxurious feeling of open space.
If you're fortunate enough to have high ceilings, make the most of a good thing. If you have a small room with ordinary furniture, make the walls an interesting design and that is what people will see. Weathered wallboards and stenciled wall paneling would suit old boards in a country home. There are many ways to enhance specific features that you love. Paint is an incredibly versatile decorating tool.
