Minecraft wiki entry for Making_nice_floors, associated text: Requirements: 18 wood planks, 18 logs
This design has a fancy and polished look. It is somewhat spareful, but not as spareful as if it were made with solely wood planks. The wood logs are hard to orient, but this can be solved by placing the wood planks first and then the logs. Place the wood logs on the back and front sides of the wood planks, to get them to face the correct direction.
