The human eye is drawn to symmetry and balance which means that no matter what happens with decorating styles, symmetrical rooms will always be pleasant to look at.
Create a Focal Point
Have a look around the room and get a sense for where your eye naturally wants to go and then create the focal point in that space.
Use Classic Patterns
Part of what gives a room timeless style is the use of classic patterns such as damasks, botanicals, stripes, and plaids.
Stay Away from Trends
Trends are anything but timeless. In fact, it's rare for any trend to last more than a few years, and they pretty much have built-in expiry dates.
Hide the Technology
Keep things behind closed doors as much as possible.
Use Quality Items
High-quality items will last for many years and will give your room a strong sense of character and purpose. If your goal is to create a look that's timeless, filling it with cheap things is not the way to go.
No matter what your preference is when it comes to color and style, it's possible to decorate in such a way that your home will have a timeless quality. Follow the above rules and you'll be set for years to come!
