    Oh Boy, some serious restraint going on right now on my part.....Ok,
    from "Jewelry Concepts and Technology" by Oppi Untracht...."When
    rolling metal, after 3 or 4 passes, depending on the metal, it
    becomes work hardened because its crystal structure is compressed and
    elongated in the rolling direction, a condition called grain flow. In
    this type of fibrous structure, rolled metal strength is always
    greatest along the grain flow direction, and weakest at right
    angles." 

    The book goes on in another paragraph to describe ways to roll in
    one direction and then turn the sheet 90 degrees and roll in that
    direction. Presumably, this would serve to keep the sheet equally
    strong from either direction when one is going to do forging
    (hammering, bending, shaping etc). 

    Although, this is not a definitive yes or no to your question (again
    restraint), I hope it helps give an idea how to keep sheet as strong
    and workable as it can be. 

    Thank you to the poster who suggested fine sandpaper for a matte,
    sandblasted look. I can't wait to try this. 

    Good Luck
    Kim Starbard

    p.s. If anyone has anything to add, would you please? I am taking in
    any and all info that I can, thanks
