    Hello Mary Beth, you'll get lots of good advice from others, and I
    hope the following will be helpful. I presume you've finished filing
    and emerying and just want to polish. After finishing with 1200
    "flour" emery paper, thin, smooth leather impregnated with a range of
    polishing compounds will give you a satisfactory finish. I buy
    aluminium strips of varying widths from the hardware store and glue
    the leather directly to the aluminium. This gives me a firmly
    resistant base which can be used like an emery buff. A range of
    compounds from the coarser tripoli, through green rouge to red rouge
    can be used with a little light oil to act as a binder on the
    leather. Cirium oxide or tin oxide can be purchased from lapidary
    suppliers and rubbed into the oiled leather for an excellent finish.
    There is also a wonderful product, diamond lapping film, which comes
    on a pale blue mylar base. It's relatively recent in Australia, and I
    have had excellent results with it, especially where I have needed a
    clean, crisp edge on platinum. However the use of this material
    presumes a flawlessly prepared surface. I finish with a circular
    motion to avoid drag marks.  Hope this helps. Kind regards, Rex Steele 
Merten
