Think of it as classic storybook illustration with less reverence and better instincts. A sky full of soft white clouds, a few of them quietly turning into fluffy dog faces. Put it up and a plain nursery wall stops being empty and starts telling a small joke you have to look twice to catch. It works above a cot, over a low bookshelf or beside a nursing chair, at sitting height so the little details land. Pair it with pale wood, off-white walls, washed linen and cane storage baskets. Don’t crowd it with loud primary-colour posters or busy alphabet charts the dusty blue does the calming, and it needs a bit of quiet around it to work. As a canvas the surface is soft and glare-free, which suits a room with a big window.
