for the dne, each wire holds a pair of stoppers. if you look closely, you will notice that the wire has a loop at the end. take your line and thread it thru the loop allowing 3 inches of line to stick out. slowly pull the first stopper towards the end of the loop making sure your line stays in place. when it reaches the end of the wire, the stopper should be pressing against your line, then continue until the stopper transfers from the wire to the line all in one careful motion (you'll notice that your main line will double over).
continue to pull, until the excess 3 inches of line passes. at this stage, the stopper should be sitting on your line.
i hope this also helps a little. they all have the same priciples. sorry i don't have any diagrams.
