Keep those other rooms in mind and measure table tops with and without the leaf, dressers, windows, wall space and end tables before you shop.
The bedroom is a great place for these heavy runners whether they are short to just cover the top surface of the nightstand or long enough to hand down the sides of a dresser.
Just add a fabric sleeve to the back side at the top or add fabric tabs and run a curtain rod through as with any valance.
This simple procedure will help bring it back to shape.
If a small amount of shrinkage is noticed the runner can be re-shaped or "Blocked".For a very attractive look add complementary colored placemats at the rest of the settings.
When choosing a runner think of its functionality as well as the design, shape and size.
