Master bathroom idea-Removing drywall and putting in a handy storage shelf. Another good idea if space is sort of tight and you want to display things instead of using a curio cabinet. You could add a door/doors if you wanted the items protected.
Put a shelf over a window and use the shelf brackets to hold a curtain rod- genius and beautiful AND gives a completely finished off look. I like the idea of having a shelf over the window in the kitchen or bedroom.
