    Of course I do not know the object you speak of but by your
    description... 

    -Flat sheet cut to the size you need for a bracelet plus some
    material (anticlastic bracelets are smaller in size than a flat
    bracelet of the same material, the more curve, the smaller). 

    - Shape the bracelet, solder if you want it closed, clean excess
    solder. 

    - Use a cross-peined shaped plastic mallet and a Sinusoidal Stake
    held in a vice
    (http://www.ottofrei.com/store/product.php?productid=6124) and start
    sinking the piece starting in the centre line (placed in the U area
    of the stake), then again next to that line on each side, repeat
    until whole piece is done (anneal and repeat as necessary for depth). 


    - Cut, add hinges, or if already open... finish as normal in other
    words. 

    - For flares and metal reduction, do these while still flat stock...
    metal hammers and metal anvil... basic silver smithing techniques...
    metal moves away from a pein/cross-pein hammer (along the longer
    sides of the hammer face)
    (http://www.fholder.com/Blacksmithing/article.htm)... 

    - Convex and near flat faces are for planishing (removing all the
    small waves and irregularities of the metal to allow a shiny/mirror
    surface to be had). Goldsmith file and sand, silversmiths do not... I
    simply use both techniques as a hybrid gold/silver smith (if I mess
    up raising a goblet I am willing to cut the lip even, file, sand and
    polish -- a European Master Silversmith would not... conversely they
    have firescale). 

    Note: For a truly interesting exercise try making a torus
    (http://en.wikipedia.org/wiki/Torus)... start flat, make anticlastic
    until you can start working the edges sinclastically, close and
    solder ... very hard on the metal, anneal often (a stake #90 or
    similar shape is useful at this stage --
    http://www.grobetusa.com/Products/formingraisingstake.html) 

    Hope this helps you get stated and to know that you can do this with
    minimal expense (even less if you make some/all your own tools). 

Kindest,
