10mm goosenecks with an 8mm entry is what ive managed to find, 6 ft with a half foot extra fabric bit. Here's the nozzle (8mm) and the body (10mm) am covering everything in gold fabric and this is the conical extension for the flower. I think you should use as thin wires as possible, threading it may be painful. We usually use a metal wire with the other electrcal wires taped to one end.
