Here are just a few examples of what I’m talking about. The pillows on the sofa look fine the way they are. They look like any other normal even arrangement.
But, add in a third component, and it changes the feel, look, and texture dramatically. The arrangement is now more appealing.
You can achieve a unique look in the bathroom by taking down the big long mirror, and putting three of the same or different mirrors together.
Hope these ideas inspire you to make your space your own!
