I came across an old hat pin which set forth the following (roughly) train of thought-

that's an interesting piece, a lot of work in that, shame they aren't used any more, do they have to be resigned to history, couldn't they be 're-invented', what if they weren't hat pins but something else, how could they be re-interpreted, how could they be presented, a block of clear acrylic - does it have to be a block............................

Sterling silver, gold plate and semi-precious stones - pin heads on average 20mm in length
