Maple shows a variety of interesting grain patterns, but the the grain is tight and smooth. The smooth finish will reveal scratches easily, however, especially in dark colors. Choose mahogany if you want deep rich colors and a satin like texture. Mahogany has a grainy texture, less pronounced than oak, and not as smooth as maple, which give it a soft, satin like appearance. Rosewood or zebrawood rails are not only a very practical option because of their durability and resistance to nicks and scratches, but also provide an interesting and beautiful contrast to the rest of the table.
Rosewood tends to coordinate best with maple or mahogany, zebrawood with oak.
Zebrawood rails on a dark oak table with navy or black cloth, for example, provides dramatic contrast. Please understand that wood is a natural substance, with many variations. All parts of your table will not be exactly the same shade, or have the same grain patterns. Expect variations, which are part of the charm of wood. Each table is unique, no two exactly alike.
