After looking at various artists, the most effective jewellery I have seen are the most expressive pieces, which demand attention from on lookers. With this in mind I have designed 10 pieces;

Netal neck collar with studding at the top and bottom and also around the bottom some cable ties. Attached onto the metal collar, a strip of metal with black Ostrich feathers.

Plastic tubes attached onto a metal collar, two strips of metal attached onto the collar with more plastic tubes.

Plastic tubes attached onto a metal collar with black Ostrich feathers attached onto the bottom.

Leather collar with studding, with cable ties on the top and bottom. Attached onto the collar, some plastic tubing and some stuctural metal shoulder pieces.

Thin metal strip with plastic tubing.

Metal neck piece with cable ties along the bottom and plastic tubes along the top.

Idetical metal collars with plastic tubes attaching them, with cable ties on the bottom piece of metal. 

Strips of leather with studding with black Ostrich feathers.

Long metal neck collar with plastic tubes.

Metal strips going around the neck and feathers attached onto them and with leather and studs on the chest piece.
