When dressing a single bed, the accessories are up to you. Have a think about what it'll be used for and how often. If it's a spare room bed, it's best to keep it simple with cushions and throws to keep the laundry loads down. If it's for everyday use, go for it! Folding the duvet about quarter of the way down makes a single bed look fuller. Add a simple throw at the bottom and a few cushions that go with your vibe for the room.
