What’s the nursery missing? Soft green with some nerve. The stripes do the steady work and the dinosaur does the talking, so the wall gets a bit of character without turning loud or cartoonish. Hang it above a cot, a low chest of drawers or a changing table, at standing eye level so it still reads when the child is small. It sits happily with pale wood, cream bedding and a soft green painted wall, and it grows up well as the cot becomes a bed. Keep the wall around it simple: one or two quiet pieces at most, and skip busy printed wallpaper or bright primary-colour bunting, which fights the gentle stripes. As a canvas, the surface is matt and glare-free, which suits a room with a big window.
