I own a few but have a great story of an exhibition down in Geelong were the main guy looking after the set up was doing a scarf hanger out of what looked like coloured vinyl, it was he'd slumped them over a tin and used a heat gun to bend them to his want in shape. When I was told how clever he was coming up with the idea he was informed by me that there was a few hundereds of dollars out of shape on the wall.
