Use an oversized urn with a sprawling palm tree. A 19th century Victorian Hall Tree in the right home would be beautiful and functional. An antique store would be the best place to look for a piece like this or better yet an auction or estate sale. Use a pair of corbels topped with marble or a pair of iron supports topped with glass for a shelf to hold a vase of flowers, keys and mail.
Give attention to hardware in the room. The switch plate cover for instance should be attractive. This gives a sense of quality. Especially in the foyer. If you can’t afford to replace your switch plate cover that’s okay, just make sure that it blends in. If the walls are painted, paint it to match. If they are papered, well you get the idea.
