Twisiting Sheet Metal

[Razzle Dazzle]

Here goes with my first question - be gentle with me as I am a complete novice and new to silversmithing. Apologies if it has been asked before - I have looked on here and can't find anything.

I have been inspired by a bracelet that I own to make somethign similar myself. I would like to 'twist' or 'curl' sheet metal so that it can either hang as a pendant or be threaded on to cord (to make a necklace). If I have done it right you should see a couple of images to give you an idea of what I am hoping to achieve. Any tips gratefully received
