<html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> What you need is Flange Cord (not to be confused with Loop Cord).  Flange Cord is available from the supply houses. It has an outer braided sheath covering inner strands.  You need to make a hard point to be able to push it through the flange holes and spring coil. The procedure is to cut off about 20cm or a little more (8 inches approx).  Peel back the braided outer cover on one end, for about 2cm (3/4 inch).  Cut off the inner strands.  Then pull the outer braid back up, now hollow for 2cm.  With a little glue (PVA or whatever), work the glue into the now-hollow end of the outer braid. Work it into a point.  Leave it to harden. You can now use this hardened end to start the cord. Push the hard end through the flange hole, the spring coil, and out through the other side of the flange.  Pull the cord through to the loose end, leaving a millimeter or so sticking out.  Cut the protuding rough end neatly flush with a razor blade, and cut off the rest of the cord on the other side too.  You now still have the rest of the cord, with its hard "leading" end, ready for the next flange. The cord really is the best thing for the job.  Sometimes people improvise with cocktail sticks etc, but they can generate noise.  A varient sometimes encountered, is where bushing cloth goes right through the flange and spring coil, and a centre pin runs through the middle.
