Ok , I bought a poster from Geahk Burchill/Castiron Carousel ,that has a New Control bar on it, but theres one string I cannot for the life of me figure out where on the marionette it connects to , it's connects to the compression bar on the controller but ?? on the marionette. I've made numerous marionettes over the years but this is the first time I've ever run across a compression bar. I know it's a specialty string but for what I don't know. Does anyone have any idea what it's for or where it connects to? any help will be appreciated
