NOTES:
-I used 20lb test fishing line for stringing the clapper to the stop. Other strings will do, but you don't want them too stiff.
-I used thin copper wire as a threader for getting the soft ribbon through the holes in bell and stop.
-If the holes are too small for your ribbon, you can use string between the stop and the ribbon and tie the ribbon to the top of the bell (of course it can get a little trickier if the holes are too small for the ribbon to pass through).
