For a nursery full of curves, this dinosaur brings the check. Round cot rails, soft rugs and rounded toys get a clean straight edge and a clear block of dusty blue to sit against. Put it up and the wall stops being a blank gap and becomes the bit of the room your child looks at first. It works above a cot or single bed, on a narrow wall beside a wardrobe, or low over a toy chest where small people can actually see it. Pair it with pale wood, cream painted furniture and plain linen bedding. Skip the busy patterned wallpaper behind it and resist crowding it with bunting and letter garlands, because the calm empty background is doing the work. As a canvas it has a soft matt surface and no glare, handy on a sunny bedroom wall.
