Take your clear nail polish and dab some across your bangle. (from top to bottom, of your bangle) lay your strip slightly slanted down on your bangle and wrap both ends inside. Now, lather it with your clear nail polish inside and on top of the stip.
Take your next strip and lay it a little less then half over your first strip. and repeat. Till you are finished. :D
(COVER EVERYTHING ON YOUR BANGLE WITH NAIL POLISH) Must be clear though. You may also use podge.
