A window treatment is a fabulous place to inject a shot of pattern or colour into an otherwise simple scheme. It's a less permanent option and offers intriguing attention to detail.

Owner and founder of Ada & Ina, Soile Makkonen says: "Well-chosen window treatments can complement the interior of a room, tying together different elements and creating a cohesive look. They help control the amount of natural light entering a room, which can reduce glare, protect furniture from sun damage, and create a pleasant ambiance. Choose colours and patterns that complement the room's decor. Neutral tones can create a calm atmosphere, while bold colours or patterns can make a statement and add character to the room."
