There are a number of customs dictating how a flag should be properly displayed: from sunrise to sunset on buildings and stationary flagstaffs, or 24 hours a day if there is suitable illumination at night. If the flag is displayed horizontally or vertically against a wall, the blue field, or union, should be uppermost and to the flag's own right, that is, to the observer's left. And the flag should never touch anything beneath it, such as the ground, the floor, or water. Within those guidelines, there are many ways to creatively display a flag, such as Martha's idea for using the flags to dress up flowerpots and planters.
