Repeating shapes in your interior design helps the eye feel comfortable and the room cohesive. This doesn't mean it has to be literal, but a few subtle repetitive shapes can make a scattered room suddenly feel connected. My personal favourite of late - circles! I like to use the literary term Alliteration to describe this method of interior design. And do note, it's often a subtle thing so if you embrace this design rule, do it with caution. If done right though, it's pretty amazing! Check out some great examples here.
