With one oversized flower, scale decides whether the living room wakes up. Go big enough and the whole wall reorganises itself around the blue. Put it up and a plain, warm-toned room stops feeling unfinished: the royal blue does the work of a bold cushion, a painted wall and a statement lamp all at once, without you buying any of them. Hang it centred above a sofa or sideboard, or on the wall you see first when you walk in. Around it, keep to warm materials – tan leather, cane, pale timber, clay pots, cream linen. What not to do: don’t crowd it with other loud prints or busy patterned wallpaper, and don’t hang it next to a second large blue piece. This one wants the floor to itself. As a canvas, the bloom reads fuller and softer, with a frameless edge that sits flat to the wall.
