Minecraft wiki entry for Making_nice_floors, associated text: Although many players make the crafting room part of their bedroom, living room, or smelting room, while others have none at all, some players with bigger houses may have a separate crafting room. A crafting room looks great with any of the combinations of wood and wood planks, or if you don't care about a fancy crafting room and want to use minimal wood, only use wood planks.
