Using cushions and throws to dress a sofa can transform a room as well bring together interior elements. When styling a sofa throw, either; drape the throw over one corner of the sofa to create a relaxed, casual look; fold the sofa throw and fold it across the back of the sofa to create a neat tidy look; roll the throw and place it at the back of the sofa.
When it comes to cushions, mix and match, but don’t over do it. For a 3 seater sofa, two cushions in one corner, one cushion in the other will suffice. Read more about cushion arrangements here.
