Stairs can be as beautiful as they are functional, the focal point of a home. Staircases are created using many different pieces to create the system, much like putting together a puzzle. Although a curved or flared stair may be most formal, use of fancy railings, newels, rosettes, mouldings, etc. can make a straight staircase much more elegant.
