19. Stepped Arch Decorative Vanity Mirror
The “stepped arch” or skyscraper profile is one of the most identifiable structural silhouettes originating from the 1920s architecture boom. Build an eye-catching desktop or vanity mirror by cutting a piece of thick plywood into a classic stepped arch—where the sides step inward vertically before forming a central curve at the peak. Secure a custom-cut or pre-bought frameless arched mirror onto the center of the wooden backing board. Paint the exposed stepped outer border with a textured stone-effect paint or a high-gloss lacquer in rich onyx black or warm ivory. Attach a small, horizontal wooden shelf tray at the base of the mirror to hold rings, lipsticks, or small perfume bottles, combining vintage aesthetic charm with modern everyday function.
