Jewellery - Development

From the File Review I have taken that the clip I produced was the most interesting looking element.  It looked quite elegant and could be developed into a stand alone piece of jewellery - a necklace perhaps?  For now I would like to continue with the bracelet I was making.
The last piece was a set size due to the angles it was at.  I want the bracelet to be adjustable, so anyone could wear it.  I need the connections to be flexible.
I will still clip parts of playing cards into the bracelet piece.  I don't think the bracelet needs to curve to support this, the card and clip should be strong enough.
The shape is too rectilinear - if it is a 'diamond' card bracelet then maybe the bracelet back can take the same form.  The bracelet back and the card could be more integrated.
What about a reversible bracelet?
