Twisted arm Chain
Rings .... lots of little rings.... I had to make 1mm wire then roll it around a piece of metal (drill bit) to make a spring shaped object, then I cut along the length of the "spring" which ended up separating a multitude of separate rings, half of the rings are then soldered closed with the other half of the rings joining up the already closed ones these are also soldered closed.
This chain of rings is then clamped at one end in a vice, the other end is held taut by a pair of pliers and twisted and twisted and twisted..... snap..... re-solder and twisted to form a really nice chain.
Ends are then cut from flat plate and soldered on and then a lobster clasp (purchased finding) is added to complete.
