There are several reasons why your home might not feel cozy, from open plan spaces that are difficult to fill in and make feel enclosed, to a lack of personal items to make the space feel homey. Try to remedy the issue by adding in personal items such as pictures and mementos, using warm-toned lighting through lamps and avoiding harsh overhead lighting, and adding in warm-toned, thick textiles to help soften the space and make it look welcoming – as if your thick throw on your couch is calling you to come and sit down.
