The transition from nursery to big-boy room has you wondering how to get from here to there. NYC-based design duo My Tiny Nest hopped on board a double-decker bus. Using Ferm Living’s Rush Hour wallpaper as a departure point, they designed a 6-year-old boy’s room to mature over time. Playful seating — like the orange pony — will give way to more grown-up options, and artwork can be added to tone down the wallpaper.
